Why are our arguments so brutal?

I'm 21 and I've been in a relationship with my partner for just under two years. We moved in together after the first year and have been living together for around 8 months.

When he first asked me to move in with him I told him I was worried it might be too soon but he reassured me and so I agreed. We get on well the majority of the time but sometimes I feel like we've become very samy. Whether it's the pressure of paying rent/bills, cleaning, cooking etc. I'm not sure.

He also really dislikes me using my phone or browsing on Facebook (he says only when we are watching films but it seems like anytime in general) Almost definitely though, every time I go out with friends for a night something goes wrong. He will drink because he says it distracts him from worrying about me.

When I arrive back home there is always and argument and we've had several breakups. It sounds petty but the fights are pretty brutal. One minute he is asking me to get a mortgage with him the next I'm being kicked out of 'our' flat.

At the moment I am at my mothers and he is asking for me to come home but I'm worried that if I move back in we'll just carry on until the next big fight. I do love him but I am very unsure on whether we are right for each other and whether we should give things another try or cut our losses now. Any advice and thoughts would be much appreciated.
