Two months of no sex?

So, my husband and I haven’t had sex in 2 months and it’s starting to wear on my confidence. When he is stressed he has ZERO sex drive and right now he’s working full time and working on his masters, which I totally get. I’m still having a hard time not taking it personal though, especially since I’m pregnant and my hormones are crazy. I just want to throw in the towel and not bring it up again. Why try to force someone to be attracted to you?
