engaged to a trucker that I love worried he is falling out of love with me

I have been with a otr truck driver for 2 years and we are engaged. We have been having some arguments lately because I miss him so bad when he is gone.

I only get to see him maybe 8 days a month! During the week we was great texting and calling constantly then he came in Thurs. said he may have to leave back out the next day. So I got a little upset and it turned into a awful argument....

Now he is gone back out and says he needs space. He says he loves me he just needs to cool off and get his head straight. Hasn't text or called me all day and won't answer mine. I'm afraid he may be rethinking our relationship.

I love him dearly and he is the love of my life! We had talked about me getting my CDL's and teaming with him, which I would try if he will give me a chance!

I text him that but of course no response... Any ideas on this? I know he gets stressed out, I just don't know what to do.
