Am i selfish ?

So I'm 4 months pregnant and me and the father aren't together. However we were for 4 years. Met up this year boom ended up pregnant. Come to find out he cheated on his gf when he made the baby. He still calls consistently. Today his aunt i had a good relationship with passed leaving 6 kids the youngest daughter of 15 I'm close to. Since we broke up last October i haven't been that close since. At 9pm I have 6 missed calls of him crying and I was sleep. so I rush to meet him to comfort him at a park. Mind you it's cold and raining and I'm pregnant. I comfort him while he cries then he said me and the baby need to go get warm. My cousin lives right across from him and she left her wallet in my car so i drop it off. And his gf car is there.WHY BOTHER ME ??????? Im so infuriated
