I am so confused and frustrated in my relationship, I need some advice.?

My boyfriend and I have only been back together about a month and yet we keep getting into fights and having stupid misunderstandings. One problem is he is obsessed with his work and just wants to sit around at his house all day and basically expects me to sit there too. I'm getting really bored. I've tried to be supportive but I'm losing my patience. I would like things to work and just feel happy but I can't. I have an anxiety problem so that is partly what's causing issues. I don't want to fight with him anymore but sometimes I feel he's being selfish and only wants to talk about his own problems and issues and that puts me in a bad mood which leads to an arguement. There is also a good chance that when we were together before he gave me HPV, so I'm feeling pretty resentful about that. I really wanted this relationship to work but I feel like it's falling apart. We're both just frustrated and I don't know how to fix it. Any advice?
