I [23F] have been with my boyfriend [34M] for about half a year. We were acquaintances for over a year before one night we both got really drunk and ended up sleeping together. This developed into a FWB situation. In the beginning, neither of us wanted to be in a relationship because we were both more concerned with our careers but over time, feelings developed and we decided to be exclusive. I understand that this isn't exactly the best approach into a successful relationship.

Things have been going well. We are both RP in nature--he is very alpha, assertive and decisive, a great conversationist and incredibly dedicated and disciplined in all aspects of life; I enjoy taking care of him, cook for him and help him do minor errands, while also focusing on bettering myself through career. We have good communication, give each other necessary space, and generally have a very fulfilling and healthy relationship. Despite our age difference, he treats me as an equal and respects my opinion. Our sex life is great, so good that we're both a little worried that our relationship is too based on sex.

However, one reoccurring problem is his view on commitment. He says he loves me and enjoys what we have, but the idea of marriage and commitment scares him. When I was out of town for a two week trip, he went to one of those happy ending massage parlours to get a handjob and ended up fucking the girl. The condom broke and he got a STI which he ended up giving to me before he started showing symptoms. After he found out, he immediately told me and we both went to get treated. He said that he doesn't consider it cheating because it was a service and that he would never attempt anything similar with say, a girl from a bar. That aspect is pretty clear, when he goes out with his friends, he makes it clear to everyone that he's in a relationship and occasionally sends me updates throughout the night so I never worried.

He explained to me that there is nothing wrong with our relationship, and I understand that as a man, he has his needs. I forgave him entirely about the situation, although I was extremely upset and my friends who I've confided in all believe that it's a deal breaker. He did promise me that something like this would never happen again and he's shameful to have brought a STI into our relationship. But it does worry me that without the STI, I would have never known about it.

Is this just a prelude to what could happen in the future? Is it futile to even continue this relationship? I love him a lot and want to believe in what we have. On /r/theredpill, a lot of men are wary about marriage and commitment and their reasoning is valid. We haven't been dating long enough to even consider long term commitment because our relationship is still developing at this point. Personally, I'm not looking to get married for at least two or three more years. My boyfriend has said that he would definitely consider marriage if our relationship does develop fruitfully over time. However, what I'm worried about is that since his mindset coming into the relationship is already like this and also considering the circumstances of how we started the relationship, it will inevitably limit our future despite how hard we try.

So, I want to ask for the insight of the RPW community--what would you do in my shoes? Would you stay with him or leave? And if I want to stay with him, what can I do to improve the situation, if anything?
