Husband can’t preform 😔😔 help

I have been ttc for over a year now with no luck.. I’ve tried opks and pre seed and nothing.. I took a break from it for a month or two because I felt like it was draining me.. this month I was all ready got another tube of preseed and a thermometer to take my temps but my husband can’t get hard and is never in the mood. He always re assures me that it’s not me he’s just too stressed over work and bills but it’s sad because it’s been over a month that we haven’t had sex 😔😔 not sure what to do or feel
