Last weekend I (36F) received an odd message on social media about my bf (33M) cheating on me with a girl from his job. We've been together for almost 3 years. He says he has never engaged in anything sexual with another individual and that he would never do so, I believe him. But this came at a point where I have been low-key questioning our relationship because of reasons that weren't yet enough to break up with him, but do bother me: 1) he doesn't have a college education, I am about to finish my PhD and I'm a college professor, 2) he cannot hold intellectual conversations with me, 3) he still lives with his parents, 40 minutes away from where I live (I own a home and haven't felt like inviting him to live together yet), 4) he doesn't earn as much money, so he takes care of his stuff and I take care of mine, which is fair, but sometimes it limits us when he cannot afford something and I can, for example, to travel, 5) his hygiene habits are not optimal, but he's been working on it since he's dating me. I already broke up with him when we were 1 year together, and then at 2 years together and it's happening again now that we were going to celebrate our 3rd anniversary. I always go back to him because he's a beautiful human being, he's caring, he's present, he's respectful, he admires me, we like the same music, have similar political & (non)religious views, laugh together and have a good time, the sex is also good. While in this relationship, I've met other people that expressed interest in me, but I can't give them or myself a chance because, well, I'm in this relationship already and it's a comfortable relationship. But now I am questioning if maybe there's someone better for me out there and a better match for him, since I might also be too demanding due to my complex nature. We've been on a break for three days, he's been texting that he wants me back and I miss him horribly, although this could be normal and some kind of "withdrawal" period. I am honestly very confused and don't know if I should go back with him or just leave him and open myself to meet different people that might be more compatible with me. What do ya'll think?
