I need a second opinion.

I’m currently having back-and-forth thoughts on my situation and I need an outside perspective. Me and my boyfriend possibly ex-boyfriend now once I get clarity on this….

A little background we’ve been dating for almost 2 years. We knew each other and met over social media. we never met in person when we were talking over social media, but we talked for about one year and then after one year we finally decided to meet up in person. It went well the first time and have basically been seeing each other and started dating since the first time we met the first month or so I was going back-and-forth to visit him since we both lived in a different state and then came up with the idea that I moved there and moved in and so we’ve been dating ever since then. We just found out during the time I was visiting him in the very beginning of our relationship he saw and slept with three people during our talking phase when I go back to my state. We weren’t a visual at the time and it was really rocky in those talking stages bc of trust and us both talking to other ppl but then after the third time of me coming to visit he asked me to be his gf. He never told me about these three ppl he hooked up before I moved there and while we were talking and the big part that’s bothering me is the fact that one of them was a trans woman….now I remember when I went back home after the second time visiting him and I had to go to the hospital bc I had somehow gotten pelvic inflammatory disease and Vaginal issues were happening, at that point you would think he’d tell me. He didn’t. So after all this time of being together for twos years this is just now being told to me and he said he had to tell me bc he loves me and it’s been eating away at him and he wants to purpose to me and sees me in his life forever but he had to come clean about that first. I am now questioning how to react and want to blink at first I’m immediately bothered and I’m pissed about him not being open and honest with me about all of that and just about sexuality and just knowing him on a deeper level in that way. I asked him why he never thought to tell me before now he said it was bc he was embarrassed and ashamed and he thought I’d leave in the very beginning if I knew this about him. Of course I appreciate him being honest and telling me that you’re but I’m more mad that he didn’t die a whole entire time. Especially because I was in the hospital and also just sexuality I think is important in a relationship and knowing the information is important.

I want an opinion on if I should break up with him over this or be understanding. He told me I’m the only person that knows about this and that he was going to go to his grave with this because it was embarrassing for him. I’m trying not to be selfish because I could imagine that can be hard to admit to someone. But I also don’t wanna stay and be a fool and stupid. Am I right in thinking I should leave or am I being too harsh and not understanding to the whole thing? Since then he’s been very apologetic and understanding that I need space and if I decide to leave, he understands and just wants me to be happy. It’s hard bc obviously we’ve had a good relationship up until this it makes me think I never truly knew him for who he was. Anyways thank you if you read this far
