Husband going back to hometown

I don't know why and I can't understand it but I kind of feel weird for some reason due to the fact that my husband's going home to see his family it's just I don't know ...I feel like I'm kind of alone here at the house and I didn't go with him because there's not enough money to go.
I guess I can just feel left out and in a way sort of like he's really not going to care about me and I know it's stupid and irrational doesn't make any sense because he loves me completely but I can't help but feel that way and I don't know why :/
