<human>: Hi Reddit,

thank you for taking the time to read my post. WARNING: slight wall of text. 

My boyfriend moved out of town about three hours away from me about two months ago for work. Our relationship has been rocky ever since; doing the long distance thing is a lot harder than we had anticipated.

Yesterday during our nightly phone call he mentioned that he was going on a trip to see one of his friends that he hadn't seen in a little while. This trip involves about an eight hour car ride one way. I asked him who he was going with and he said it was with one of his female friends. This female friend, he says, is one of his best friends exes and the three of them had lived together before in the past. From what he says, she had sent him a facebook message asking if he wanted to come along on the trip to visit their mutual friend. 

I am not comfortable with this at all. My SO and I had talked about doing this trip together all summer; I definitely wanted to meet his old friend and make the trip down with him.  So for him to randomly go with another girl without inviting me is worrying me. I am dissapointed, feel left out, and am very jealous of this female friend of his.

I expressed these things to him and he was not very understanding. I tried explaining the scenario to him: ''Let's say I went to.... say California for a few days with just one of my buddies.'' His response: ''I would break up with you if you went to California because you probably wouldn't come back.'' Not sure where his logic came from, I have talked about living in Cali for a little bit after school, but have never implied dropping everything and never coming back. I really wasn't sure what to take from that. 

I'm very confused and jealous, any advice on the situation would be appreciated.
