Distance 💔

So....gosh I don’t want to sound ungrateful here or come off the wrong way...but my my fiancé started a new job 3 months ago, he stays 2 hours away from home all week, comes home Saturday night, and leaves Monday to do it all over again. I know it’s tough on him and he doesn’t like it very much either but he does it to support us and our son. Lately he goes out with all his friends every night, which is fine, but...I guess I’m just feeling left out. Im home watching our son, which is a blessing and I’m so grateful to be a stay a home mom and that he takes care of me the way he does because he doesn’t have to...it just sucks. I miss him and am stressed because we are getting married in 14 days and Im dealing with all the frustrations of that plus raising a child basically it feels like on my own. My son is teething and getting 4 molars at once so he’s not a happy camper and the past week has been rough. I guess what I wanna know is how do others deal with the distance? Never getting a break? Insecurities? Cuz lets face it...we are all human and we have them. Someone give me some advice please! I get that he’s really not that far and I should be happy its not even further but we have been together 8 years and this all brand new to me.
