My boyfriend of 2 and a half years is ignoring me

Ok so 2 and a half years. Whenever he gets mad he shuts me out he is beyond wonderful when he's not mad. Treats me like gold. Apparently when we talk and I go to interject he gets mad and says I don't listen, how am I suppose to know when I should not speak at all. I thought conversations and arguments are 2 sided. I told him you need to tell me to not speak until your all finished so I know. It's just unbeliabme to me. We live in an apartment in his town we pay 1400 a month. I left my town and said ok we can live here. Recently I've been thinking we have been here for almost 2 years maybe we get a cheaper place once the lease is up, I didn't think there was a problem making a suggestion. He gets all devensive and says where are we going to go all this stuff. I knowthere are many others places cheaper. And again just a suggestion. We went to breakfast on sat and that topic came up and he got all mad. In my mind I was thinking about saving for a house in the future. It's hard when rent is so high. Also I know I need a new job first to get more money and. I told him I agree with that. So we got into the car and he started to talk and I interjected to say something at the end of his sentence and he freaked out called me a bitch and he couldn't stand me. That I always interrupt him. Again. How do I know when to not talk. I don't mean to cut him off his feelings are important to me. He's told me in the past. Let me talk then u can. Ok fine. That's fine with me. So after he yelled. We didn't talk that night. We had friends over but he ignored me. And the. The next day I texted him because I took my dad to a cruise I said we need to talk and I tried multiple times yesterday to talk to you and see what you were feelings and what was bothering you and you didn't want to talk He said leave me alone you are not helping me want to remain with you. Again. Leave me alone. Listen to this and stay at your dads while he is away. I replied said I couldn't someone else was there. So he said ok leave me alone then So after that. That was Sunday I haven't texted or tried to talk to him it's Tuesday morning , if he needs his space for reasons. Ok but to go on this long. It's been a couple days. I wondering if it will be all week. How long do I wait. It's tearing me up inside. I know I should show weakness but it hurts. It's frustrating. I want to talk out our probelems. Not stall. It doesn't make sense. So I guess I wait. But how long do I wait. I'm hurting. And he knows that I junk. I told him sun morning before I left with my dad that it hurts when he does this and he says well it's all about you huh. **** off. It's not all about me. I tired to know what was wrong with him and I'm giving him space. He's the one to seem to not care about my feelings. I feel broken and constant pain in my heart. What do I do. I just want to talk. I know he loves me and I love him dearly but this just hurts so bad.
