Ok- I need to vent and I need some honest feedback here. My husband and I got in an argument this morning and I can see his side of things, but I don't feel like he's seeing mine. Let me lay the background: 3 months ago my husband's oldest son from his first marriage was diagnosed with leukemia. My step-son and husband traveled from our home in Alaska to Seattle for my step-son to receive care. My husband's ex-wife lives in Seattle and she was quite hospitable to my husband, frequently taking him out to dinner (with my step-son and her husband) or lunch.
My relationship with his ex-wife is rancorous. She was a childhood friend that shunned me once we hit high school because she was in the in-crowd and I was not. She would only hang out with me if no one cooler was available. She got married young to the man who later became my own husband. We lost contact after high school entirely.
10 years go by and I ran into the man who would become my husband- he tells me that he's getting divorced and the divorce is to be finalized 3 days later. I had recently gotten out of a relationship, and a few weeks after his divorce he called me and asked me out. I accepted. We began dating- the rest is history- we've been together 18 years now. I should also mention that at the time of the divorce, his ex-wife was already living with another man (who she later married and they remain married to this day also).
However- his ex-wife has gone around telling a number of our mutual friends and acquaintances and family that I busted up her marriage. She told people I had always wanted her husband, that I'd always been waiting in the shadows, and that I'd told him that she was cheating on him and that's why he divorced her, and that I was a home-wrecker. None of this has any basis in reality or fact.
My step-son is home for a couple of weeks and my husband wants to have a BBQ at our house and invite family and friends. His ex-wife is also up here (her father still lives here) and my husband wants to invite her as well. I do not want her in my home. He feels that because she was hospitable to him when he was in Seattle, that he should return the gesture. I understand that- and yet I still do not want her in my home. He thinks I'm being petty. I acknowledge this is a possibility. I take it very personally that she has told people I broke up her marriage. I am not a homewrecker, and I did not have a single thing to do with the demise of her marriage. I am angry, in return, because it feels like my husband values her good opinion of him more than he values my feelings on this issue. He says it was 10 years ago she was saying these things, and that I need to let it go. I'm not so sure it has been that long since she's said those things because my step-son's significant other made a comment over Christmas that indicated she's said something more recently. I have never said anything to the kids or anyone other than my husband about this and my husband never says anything to anyone either so any ideas the kids or their SO's have gotten would have to have come from her.
I've tried to present both sides of this. I do understand my husband's position. I probably wouldn't mind inviting this woman to a dinner at a restaurant...but I really just don't want her in my home. My home is my sanctuary. I would never try to invite someone to our home that my husband didn't want there, nor would I try to convince him he was wrong about it.
So- feedback. Am I being completely unreasonable? Do I need to set this aside and be the bigger person and allow my husband to invite this woman to our home?
