Guilt over ending a relationship?

Hello. I am 100% aware that I know that I am the only one who can truly make this decision. I just would like some others to weigh in or just to let this off my chest. I have been dating my boyfriend for close to 2 years. I am recently thinking of breaking things off before we graduate from university. I feel really guilty about it however. I can’t get past this feeling of guilt, especially since we are in a good patch right now. However, we have been fighting a lot, and there are several issues that keep coming up. I am struggling because i have tried to communicate my feelings to him on multiple occasions, but he is always distracted and doesn’t listen to me. I know that I am not perfect but I have had the same issues with him the entire time of our relationship. I feel like he doesn’t respect my feelings or my values and constantly wants to joke around. Theres a lot of topics we can’t talk about because we just have two very different views and won’t agree. I really don’t mind hanging out with his friends but he always makes plans with them and then invites me afterwards like as an afterthought. He recently took one of our breaks that we planned to spend together and invited all of his friends. I tried expressing to him how I felt but he called me irrational and inflexible. He says that he thinks I’m a diva and high maintenance because i wanted flowers for Valentine’s Day and I was upset that he didn’t get them. my communication doesn’t seem to get through to him, and I don’t think I’m being treated well. I feel like it’s been one sided and I’ve done all I can. I just don’t really know where to go from here besides breaking up
