I (32 F) and my bf (30M) are in a long distance open relationship (primary with a lot of emotional intimacy and sexual chemistry). I am going to meet him in a few days after 9 months. But just this whole week he is spending time with another suppossedly casual partner. I am not dating other people (I think i am inherently monogamous but I am not averse to exploring). I am having a hard time accepting the fact that he wants to spend time with someone just before i will be arriving. I was very excited to finally meet him but now i feel like whether he even missed me. The worst part is i let him know that I am not okay with him meeting his other partner week prior to me visiting but ultimately left the decision to him. He decided to have not one but multiple dates with his partner. Tbh I am feeling very jealous and a part of me feels like I wont be able to get intimate with him when we meet. How to deal with this? I feel like he isnt as excited as I was and my excitement is fizzling out too and I am second guessing it all.
