Should I cut ties with my homophobic mom?

I started having fantasies about the future. I want to badly one day to get married with a man, have three kids and maybe a couple of dogs. I deeply have this desire on me. I want to build a family. But my mom wouldn't be part of my life at this point.

She absolutely hates gays, today she was talking to me about a law in some country where gays receive death penalty, and she said "That's how it was supposed to be everywhere, don't you think?" I immeadiately tried to changed the subject but she kept insisting "DON'T YOU THINK?!" so I said "yes, yes". If I'd say no she would have suspects, and the last thing I want is her knowing that I'm gay.

So, this is it. She wants to see her own son dead.

But don't get me wrong, guys. I love my mom. I surely do.

She's always done everything she could to raise me well, as my father abandoned us. She always bought expensive gifts to me, such as cell phones, notebooks, records... And I have a good relationship with her, she always gives me advices when I need. She is a good mom, I'd say. Except for her homophobia, because to be a 100% good parent you need to accept your child no matter what, with the condition that he/she is not affecting anybody's life. Whom am I affecting for simply being gay?

I don't blame her. My grandfather was a great homophobe too, so he actually taught all of his children to be this way. It wasn't her fault, she simply wasn't born on a decent enviroment. She is what her parents made her.

Back to the point, I want to have a family. With another man. She would never accept that. Seeing her own son marrying another man would be a gross vision for her.

Please, PLEASE don't tell me to be honest with her and just rub on her face that I'm gay. Things are not that easy. Just because your folks are open-minded doesn't mean everybody else will be. She HATES gays, come on! She supports death penalty for us! She would never accept me as I am.

She would expulse me of her home, shout curse words against me, maybe even hit me. And tell me to never come back. Once my mom puts something on her mind, nobody can change it, she's very unreasonable. So I couldn't ask other relative to talk to her aftermath, specially because EVERYBODY on my family are homophobics. Yes, this is possible! An entire family! I don't have support of absolutely anybody, so the day I come out, I would be alone on this world.

There are some gays that leave their family behind and go be happy if they cannot accept them. But I don't know if I can do it. I'm my mom's only child. She has only me, as she has no husband. If at least I had brothers or she were married... that just make things even worse.

I would probably remember her everyday, thinking that she's getting old and I'm not there to take care of her, she will be probably watched by a nurse and not her son...

I don't know what to do. I want so badly to have a family once, but just knowing that my own mother would never respect that, my children would never meet their grandmother, my husband would never meet his mother-in-law, and she wouldn't be part of my happiest moments (my kids being born and my marriage) it really hurts.

So what do I do? Do I cut ties with her then? But the image of her growing old without me breaks my heart. Do you think that on her final moments she would get rid of her prejudices and just call me to see me for one last time?

Anyway, I really needed to get it off my chest. Sorry for any writing mistake, I'm in a hurry here and I don't have time to correct it. Thanks everybody who read it, it would be friggin' sweet if you have an advice. I really need it.
