I've met this girl, but is it fair to start a relationship with her?

Hi, for those who don't know, I am transgendered, so I'm female in a male body. Since I came out here on EC & to a couple of my friends, I've also come to terms that, since I'm only attracted to other women, I'm also gay. This has been a bit of a relief for me to finally know & accept myself for who I am.

The problem I am facing now is that I'm considering a relationship with a woman my age. We've known each other for a couple of years. We actually met when I started going into one of my local McDonald's stores for breakfast every morning (she is one of the managers) & Joan was behind the counter & we hit it off with each other. Even tho she was already dating & living with someone else, we still enjoyed seeing each other for that 5 minutes every morning & I would go out of my way to go to that location just to see her everyday. I liked her & I was pretty sure she liked me too. She is also a mother & that didn't bother me at all about her. So, for a year, I would see Joan every day, right up until she went on maternity leave (she had a baby girl with her now ex-bf). I still went in for breakfast for a bit after she went on her mat leave, but it wasn't the same, so for about a year after up until my workplace was closed & didn't see her. I also stopped going in as the food was causing issues with my health & I needed to address that quickly. So it had been about a year & a half since I'd seen her.

On Saturday nite, I went to a concert & ran into a former coworker of mine, who was with a couple of people he knew, one of them was Joan! At first, I almost didn't recognize her as she had gotten her hair cut into a very short but cute style & had dyed it from red to black, which looks good on her as well. So, since neither of had recognized each other immediately (I have let my hair grow much longer since the last time we had seen each other), I pointed out that we did both know each other, & when she realized who i was she got a big smile on her face and was happy to see me & even hugged me! She also told me that that nite was her first nite out as a single woman, which I will admit, made me a little glad, even tho I said I was sorry to hear things hadn't wworked out. She jokingly had said to the other guys we were standing with that she had heard that a woman shouldn't have to buy a drink when she was out, so I jumped at the chance to buy her a drink. She had said to be careful around her that nite, as her ex-bf was there as well, so we were both friendly but casual for the whole nite.

During a break in the bands, while the headlining bands was having their crew set up their stage, sound & gear for them, I spoke with my friend, & he had told me that Joan had told him that she had 'had the hots for me'. when I asked him what her exact words were, he said that she really enjoyed & liked when I came in to see her, she had told my friend that even tho she was dating someone else then she 'had the hots for me the whole time'. I will admit, I was quite happy to hear this as I was attracted to her before when we had first met & even when we had a platonic, 5 min relationship in the store every morning, but seeing her having such a great time & enjoying herself & especially outside of where I had only ever seen her before, I found her even more attractive that nite. At the end of the nite, after the show, we were both next to each other after the merch table had been packed up, so I looked at her & asked her if her ex was still there. When she said he had left a couple hours before, I said that I was glad, as I had wanted to do something all nite. Then I kissed her. And much to my own happiness, she totally kissed me back! It was sooo wonderful!

Now to the issue I've been sort of trying to get to now. I'm transgendered & I've decided that I must fully transition, including hormone therapy & GRS surgery to correct my body so that it matches who I am on the inside. I really want to go out with her & we've even made plans to see each other again on Thursday nite for another concert, & while I'm not expecting anything to happen quickly since she just got out of a relationship, I am afraid to start any kind of relationship for a couple of reasons. I've been a little bit lonely for a few years now tho, so I want to be in a relationship with someone I really like at the same time.

Is it fair for me to want a relationship by having to lie to Joan about who I really am & that I intend to correct? Is it fair to Joan that I start a relationship with her, only to eventually tell her that I am transgender and very possibly risk losing someone that I really like now but very quite possibly may come to deeply care for? Should I avoid relationships with any woman until I've had hormones & surgery & can be an honest relationship with another woman? I'm really not sure how to handle this situation & I don't want to hurt Joan's feelings plus, since she's also a mother, I would expect her reaction to be that she wouldn't want someone like me being around her children once a possible relationship might have gotten more serious & I have waited until then to come out to her. I'm just really note sure how to handle this, all I know is that I really, really like her & want to at least spend a little bit of time with her & see where things go. I just don't think it would be easy to have to lie about myself...

Sorry for the long post, but it's something I've had on my mind since Joan & I reconnected this weekend, and especially after we had kissed. Any help or advice would be really helpful right now...
