Honey I'm sorry..
Listen, one thing i've learned out of my relationship is that communication is key and that's what's going to keep your relationship is strong. It's not easy, but if there are trust issues or any other issues floating around, you need to be open and honest about it and talk to him, and he needs to talk to you. Even though we are in relationships, sometimes we disconnect from our partner, usually due to stress and misscommunication.... we all once in a while need to step back and reconnect with our partner. and the suggestions about the pros and cons list is a fantastic suggestion, it's a very concrete way of weighing out your options and concerns.
Good luck and we are all here for you!
