Any bisexuals decide to just date the opposite sex?

I'm so damn lonely. I know I could be equally as lonely in a heterosexual relationship but being in a homosexual one just adds to my loneliness.

Just about everyone knows I have a female partner. We've been living together for years. I feel that our relationship may be coming to an end and I just wonder if I should just try to go back to living the straight life if it does end. I know that I'm not straight I realize that. Though I consider myself bisexual but naturally since I've had a female partner, I haven't had sex with a man in so many years since we have been together.

I'm not out at work or in my professional circles and I'm just not going to be. That being said, I know I'm not living as authentic as I should or could. I'm still not going to come out professionally. It has consequences that I do not want in my life.

I'm wondering if I should just try to find a man and stop complicating my life more than it has to be. Life is hard enough without adding the whole lesbian thing to it. It's not like I feel so fulfilled in my lesbian relationship that it makes it all worth it.

I don't really know what I'm posting here. Just wondering if there are any bisexuals in committed heterosexual partnerships that are on this site.
