Hi Dinosaur,
Your post really stood out to me and so I thought I would reply and try and give you my input/advice.
I hope it helps:)
It seems to me that the fact your boyfriend is moving away for work in 5 weeks, might be the reason you two are experiencing what you are experiencing now. He is probably wondering if you guys have what it takes to last the physical distance his move would create between you or if he would want you to move with him.
A life move like that could just honestly be making him think about his life. What he wants. Who he wants.
Sadly you do have to be open to the possibility this may not include you. I’m sorry. I know how hard that is to take and accept.
The one thing I think it would be great for you to accept is that no matter how much you love this man, he will need to do what is best for him. As you also need to do. Take some time to thing about how you feel. How do you feel that he is moving across the country? How do you feel now that he is having a “wobble” and you are not.
I hate to say it but time apart a “break” may help you both see what it is you truly want.
