All alone long rant

A.

So this past Friday my so got really mad at me because I ask him to move over in my and then he started yelling in my face so I got up and slept on the couch. Saturday we had plans to with friends and yard work. He left Saturday around 11 saying he will be back in a hour of two. Never heated from him all day or Sunday. I was texting and calling everything to try to get in contact with him to make sure he was ok. He finally txt me back after I sat I was going to call his mother. Then he comes home about 6 and ask me why I won't talk to him. He left and will only talk to me after I said I was calling his mother at 9am nothing else and all he said was he is fine. He was at home maybe 10min and said I feel like u don't want me here and I said yes. He started packing a over night bag and told me to call him when I get over myself. I was like really you call me when u want to be here with me and when you want to stop picking fights. He said I was full of bullshit and need to stop lieing and left. The last couple of months over the littlest thing he been picking fights. I feel like I am done I am not sad he is gone I just miss him and I don't know what to do I feel like he will do the same thing again if I let him come back. I will fine out next week if I am pregnant with his kid we been trying for 4 months and it was his idea.i now feel like he was trying to trap me and idk what to do with the whole situation. Like should I forget about what he did again and let him live in my house or just move on. I just need someone else point of view. Thanks all
