I'm freakin so out...

Sonia
My husband was married to his ex wife for 15 long years hand has kids two kids with her.
He got a vasectomy when he got the second child because she wanted him too. After we started dating he didn't told me anything and the knew how much I wanted kids but he kept it a secret until the day when his stupid ex wife told me... You could hear in her voice how much she enjoyed telling me that..
After that I told him what I heard and he showed me papers for a vasectomy reversal in January 2015. Wich we got. But it didn't worked out and he had to have another surgery in September 2015. She didn't knew anything about the second one but she found out the first one didn't worked out. 
Now she's always making fun of me on her fb. Posting things like "I'm so blessed with my children... Thank god I was able to have two.. Some aren't, and that's for the better" or "poor young new wife, you will never know how it is to be a mom" or simply just fun out of me. It's getting to me so bad. We still didn't got our BFP and it's just what we both want. The last weeks I'm crying a lot because she won't stop putting my name in her mouth. She even told the kids not to talk to me when we have them. I feel sometimes so lost. And I miss my family back in Germany. I feel like I won't be able to have kids and my husband doesn't want to adopt. Right now it's so bad I need to let it out. It's just a day where I sit in the bathroom and cry  because I feel like my life is not falling into place at all 😭😭. And she is making it just worst ...  Oh and the most recent news are that she and her boyfriend are trying for another baby... Which I know will happen. 
I'm so upset about my situation ... I can't help but cry.
