Pregnant, divorced, 2nd marriage

Flor
Anyone on here on their 2nd marriage? I am having DH n & I's 1st child together. He has 2 n I have 2 from previous marriages. We r over the moon. Been married 3 yrs. My ex was cool when he learned the news but his ex is having a cow. Causing drama, now not wanting to lend him their kids n talking very badly about us to the children. We know Cuz kids 9 & 10, tell us. But do they r starting to believe her poison. I can't stand this. Every few days it's something. I am 13 wks pregnant n I don't need this crap? Anyone gone through anything similar. It's not like this was new to her, like I said we've been married 3 yrs. The only thing new is that we just bought a house n were finally blessed w our little peanut. Also it's not like their divorce is fresh. They had been divorced 5 yrs when we met. Please give me some advice...
