Me and my partner are going through a rough patch and I don't know what to do ?

me and my bf of 4 yrs are going through a rough time. We in LDR and planned to meet again in 2 weeks time.

We been arguing lately over the silliest thing and know how to make eachother mad.

Most our argument is about him not being romantic, stubborn, which makes me upset and over analysing and reacting. His respond to me be is negative too. Or he argue with me in front of his mom and makes me look bad. Today we had big argument and he said that I am hypocrite and have negative thinking sometimes. We been having issues for the past two weeks. We argue then the next day wer ok and so on.

Today it got heated and we said mean things to eachother. He said he no longer want me and I said to him you're doing this cuz you don't want to put an effort to see me. He said you're childish, leave me alone now and go date you're ex. Go block me on you're phone and I will block you out of my life. He also said I am bad person! After 4 years of been together he now think I'm bad? If I am bad why is he still with me?

I started to doubt myself now!

Then during the argument my body started shaking and I had to end the call. He stared calling me consistantly but I couldn't answer the phone and have not spoken to him since.

This is the first time it get heated like this. Otherwise the general relationship between us is good. We have very intimate and strong bond apart from those argument that happens between couples.

I don't have any friends or sister to talk to. I need genuine advice ?
