Is our Relationship over?

My boyfriend and I had a argument Saturday night. He told me we weren't together anymore but we would live in the same house for our 3 year old son. It was time to go to work so I stormed off and went to work. Every since then we have been talking only on a as need basis but have been doing so pleasently. In the past if he is mad we don't talk until we fix it. He has also been cooking and cleaning (which he never does). Our son needed pull ups and I asked him for money for them and he gave me money with no issues (he normally whines about having to give me money) He also told me the washer was ready to use to clean my guinea pigs fleece. We also have been sleeping in the same bed. So I'm wondering is it over or what? We are not having casual cuonversation or no physical touch. So I'm wondering is this his idea of how it is to live together without being together or is he sorry about our fight ( he never can apologize but tries to make up for his actions). Tomorrow is our day off so we will see if we go out and have our normal family day or what. Im avoiding talking to him right now because I just don't want to fight. However I cant live in a house with someone that don't want to be with me.

Yes, you need to talk to each other and sort it out! I personally don't feel its over. It could just be that he is waiting for you to make the first move. Speak to him without accusing him. Its when you accuse the fights start. Mistakes all of us make. By pointing them out it will only lead to fights. So when you discuss, keep the blaming game apart and have a discussion instead on what each partner's expectations are from the relation and both of you try to match that up.
