Genuine relationship advice please

Can someone advise me please as my mind is everywhere right now.

My boyfriend of 6 nearly 7 years has been going out a lot more than he ever has done. We moved into our own place this year in June and recently last 3 weeks we haven’t spent any time together.

He went to london with a group of guys and he didn’t return home and never heard from him AT ALL until 1pm the next day to find out he got very drunk, battery went and stayed at his friends. Of course I wasn’t happy I was worried but also angry with him because I thought the worst.. he hasn’t shown love & affection for quite some time (spending time with me and taking me on days out) everytime we did things it’s always been my plans and my ideas. I feel really hopeless right now and every week ever since he’s been going out and coming back really late! He’s been popping out for these “30 min” cigarette breaks which is starting to make me think.

We got into an argument tonight because I told him I can’t deal with any of it anymore, feeling lonely etc. he’s gone out with his football crew since 6pm and he’s not returned home once again.

What do I do? 😭
