What do I do? *updated*

So my boyfriend and I have been together about a week and a half (pretty soon to have problems I know) and my grandpa passed away the day after we made things official and his funeral was last Sunday. Well Friday we had the family only viewing, Saturday was family and friends, and then the burial was Sunday. THE WHOLE TIME I’m dealing with this and trying to focus on the situation and family, he starts arguing with me. We’ve argued the past six days. It’s driving me insane because it’s so soon in the relationship and WHO ON THIS EARTH argues with their SO before and after their grandfathers (the most important man in their life) funeral. I want to break up with him because I’m no where near happy but part of me things it’s so soon to break up with him and part of me wants things to work out. I’m 17 and this is my first relationship so I just teellike I need it to last longer than a week or two. But I don’t like dating someone who is willing to act like that.

UPDATE: I broke up with him.. when I tried to talk to him about it he would say he thought he was helping (even when I made every clear he wasn’t) and kept downplaying my feelings. I read the comments and they helped me grow a pair and realize this isn’t right so thank all of you ❤️ it also really helped a lot when I realized pawpaw wouldn’t want me with a guy who would treat me like that. I hope he’s looking down on me telling me good job 💕
