question for all the lady's that are going through this god I hope I'm. or the only one 😐

I am 25 weeks pregnant this will be my second child there is a 10 year gap between my first. Born to this one after so many years being told I couldn't have any more 10 years later hello positive test 🙂 but I'm big question is I feel that my partner doesn't want to be intimate with me and it's driving me crazy and he just doesn't understand he's always tired or comes up with some odd reason not  to sleep with me anymore am I over reacting ???
