Would you feel some way?

Me

My boyfriend had a girl pregnant he was with for 3 minths before we got together. She had the baby 3 weeks ago we both went to hospital will she was in labor an even stayed the night and all 3 of us was cool with it. She lives in Ohio an us in Indiana so going to see the baby is a two hour drive but hes been speaking of going to see him again with his family but not me. I want him to see his child as much as possible but even though there just friends it makes me very jealous an upset he would attempt to go without me even though his family wiuld bewith him so its not just him an her. Would u feel the same way or ne ok with it?
