My feelings are mixed but empathetic. Your ex-bf was pressuring you, which is never good. Instead, it should have been an ongoing conversation (not argument) about how your coming to terms with sexual fluidity and lack of disclosure to loved ones impacts the relationship. He should have expressed the importance of affirmation when being in a relationship, because certainly you would have given that affirmation to a female partner. This situation can lead him to feel insignificant and cause harm to his emotional well-being. Personally, after having been in a couple of relationships with men who were closeted, I now know not to commit to anything beyond a FWB arrangement with somebody who isn't out. To enter into a deeper, more romantic relationship with someone who hasn't come to terms with his sexuality, nor expressed it to family and friends, leads to a lot of frustration for the person who is solidly out and confident with his sexuality. I don't know who initiated the path toward becoming more deeply involved, or if it was a mutual, organic evolution, but please, do not seek out a romantic relationship with a same-sex partner until you've come to terms with your sexuality and feel confident with expressing your love for another man to others in your life. Otherwise, if you're seeking that kind of loving relationship, but have no plans to affirm it, then--and I say this as tough love--you're being selfish. Consider what that might do to the other person and put his emotional needs above yours. That said, I'm sorry it happened this way, and I hope you work through it to the point where you can be comfortable with yourself and future relationships. Cheers!
