Relationship failing

Hello!

Me and my boyfriend have been together for four years. He just turned 21 today and I am 20. We have a one year old together. Since we have had our child our relationship has honestly went down the gutter. We seem to argue almost all the time. The arguments are about petty stuff. One thing that is the biggest right now is him playing on games which seem endless. He will play almost all day and night.

He will take maybe an hour break or two then hop right back on it. I am really starting to get annoyed because he gets irritated if I ask him to get off of it and spend some family quality time. I try my hardest to try too because our daughter is only going to be one once. It is bothering me to no end. He is off all week and claims there is nothing to do. It is like take care of your child. Or atleast help me!

Today he turned 21 and I am really happy for him but he is going to be out all night and day today drinking and getting drunk with his friends. I guess I have anxiety about him getting too drunk and hooking up with ladies or getting their numbers etc. I know it is childish, but I just have that worry. Is there any way to help me not feel so worried!
