Husband baby crazy...and I can’t seem to get pregnant!

My poor husband! He wants/needs a baby! We’ve been diagnosed as “unexplained infertility” after a batter of test done over the last year and a half. We’ve done medicated cycles, even a failed IVF cycle. I’ve been poked and prodded so much... we took a few months off after the failed IVF but this month I thought I’d try IUI since it wasn’t as expensive and we haven’t done it. (I needed something not as heavy) my new doctor wanted to do a water ultrasound just to check out my uterus lining...she finds a super small polyp. Great...now I have to have a surgery for the “chance” it could or could not be interfering with pregnancy. I’ve never been pregnant, ever. We’ve been together 6 years... I’m at my wits end and there seems to be no end in sight. I’ve conceded that this isn’t in my cards...my husband however hasn’t. Worse thing is, he tells me he’s ok with whatever then tells his friend something else.

I’m just venting and upset. I really have no friends that have gone through this...all have kids and are currently pregnant or have 3...

I’m tired of testing...tired of trying...I don’t even enjoy sex anymore... I feel like I should just divorce my husband so he can start again with a younger woman...
