Please help... long post

Okay I need some advice/help.

So my husband leaves the 1st of October to go on a month long trip for work in California. We just recently moved in to our new house about 2 weeks ago. Since then, we have not had one night to ourselves because his bestfriend has been here every night. I will cook, and he shows up to eat and then will leave around 11-midnight. We went to my parents Thursday night, and my dad was cooking steaks for us. And here comes my husbands best friend with his own steaks (which was fine) but just the thought that we can’t even have a family night is seriously getting on my nerves. I talked to my husband last night about it, because I’m trying to spend as much time together as a family with him as much as possible, cause I know for that whole month we’re going to miss each other so badly. Our 2 year old doesn’t understand that dada has to leave for work. But anyways, this morning guess who comes over 🙄 his bestfriend. And turns out he’s going to be living in our camper in our back pasture, renting it, because his girlfriend left him. I’m all for helping someone out, but I can’t do it with him. I’m 20 weeks pregnant, and he wants to stay until 3 months after the baby is born in Feb. what in the hell do I do? I don’t want to come between my husband and his bestfriend, but I am so tired of him!

Sorry this is so long. I just have no one to talk to about this.
