Okay, all you mothers out there...My FI and I have been together for 5 years, and a few months ago we told his parents that we're getting married. They said, "okay, good" but that's about it. His mother and I have always had our ups and downs, but lately things have gotten terrible.She didn't like our location. My FI tried to calm her worries about it but also firmly told her that we deserve the wedding we want. (note - she's not paying for it)She didn't talk to him for weeks. When she finally did answer the phone she said I control everything that he does, I write speeches for him before he gets on the phone with her, I ruin his life, etc. She said if he was going to keep behaving this way she wouldn't come to the wedding - in fact, she said he'd have to choose me or her. FI says it's not that big a deal because she won't follow through on these things. To me, it's a big deal because all of these things really hurt him. Of course he wants her to be there, and be happy for us. He thinks maybe it's because she doesn't know me "as a person". Is there anything I can do here?
