I’m an idiot

Today me and my boyfriend planned on going to the movies to spend time together, little did I know it would go the wrong direction. This past year I personally have had financial issues and he decided to buy me a phone “iPhone7” all I had to do was pay him $50 for the bill. This last month I couldn’t pay it because bills needed to be paid “water,light,insurance etc.” . He then goes on to say “I’m done”. I ask him to explain what exactly he’s done with and he says that he feels used that because I can’t even pay the phone bill so being me I start crying feeling overwhelming and he has the nerve to just be on he’s phone going through social media while I am pouring my eyes out in front of him. I then just walk out start walking and call my friend to pick me up. Minutes later he texts me saying “ I made a mistake, I don’t want us to end”.
