help is there something wrong with me?!

I can't stand the thought of leaving my baby overnight or my husband leaving overnight. She's 5 months old. Let me explain : we had planned to go to Austin to see our favorite band (Muse) and it's too far of a drive to come back the same night - so we'd be leaving her with my mom (who is her primary caregiver when I work and I 100% trust her and my daughter adores her). Then in July my husband wanted to go to a soccer game (his passion and favorite team - Man City) is coming all the way to Texas (Houston) - which is a once in a lifetime opportunity (we did go to Manchester England in 2015 to see a game). We can't afford two tickets - so he'd be gone for 2 days.
