To go out or not to go out.

Me and my partner are trying to work things out, me and my friend planned this birthday party for about a week, I told him that I wanted to out out. He was really annoyed at the situation and said to do what I want.

He then turned around to me and said how are we meant to try when you no I don’t trust you and u want to go out. I no if I go there is no hope between us but if I don’t go I know my friend will be really annoyed and properly won’t talk to me again.

Am sooo confused I really don’t no what to do anymore. Please help me 😞😢 I seriously need some advice from females with partners and just females in general.
