From Berkeley To Heterosexuality: A Question For The LGBTQ+ Community

I guess I am asking a question of other lesbians or bisexual women. I am 31, I went to college at UC Berkley, both for an undergrad and for grad school. During the time I was there I had three girlfriends, nothing spectacular. After I graduated I met and fell into a very deep relationship with a woman Child Psychologist. I suppose sex is always the first step, deep feelings followed later.

After six years she confessed to me that she had been seeing a man for a while and she was going to live with him. We had a very emotional goodbye, she couldn't explain it and neither could I. I left California and returned home with my parents. My mother's group of friends included a divorced man, an Architect. He pursued me and at a given point I decided to let him get what he wanted, I wanted to find out what it was like, maybe so I could understand what had happened with my girlfriend.

I want to say that I went along but really I just gave in. Weeks became months, months became a year and I was his girlfriend to everyone in town, frowned upon because of the difference in age, but his girlfriend in everyone's eyes but mine. He asked me to marry him, I didn't answer and hurt his feelings. I apologized and agreed to marry him. I am now married and I am expecting for August.

My girlfriend in California is happy for me, happy I found a man for me. She swears that once that man comes along the spell is broken and you follow your true heart. I don't know, I am not unhappy being married, I am expecting. I miss my girlfriend, I miss her terribly. We talk often, we aren't looking for a sexual life together, but we need to be attached to one another.

My question is how common is it for lesbians to have the spell broken and move over to a heterosexual life?
