I'm sorry if this has been put in the wrong forum category, it's kind of half rant/half please advise me!
I seem to have mortally offended my FIL. We have a young son and some months ago when the baby and I were sick he turned up unannounced and I asked my husband to please ask that he ring before turning up in the future, which to me seemed completely reasonable. My husband did so, and my FIL made the accusation that my MIL had put him up to it (they are divorced. It is not friendly). My husband had been up all night with sick baby/wife and had very little patience and told him that he was being ridiculous and sent him away. Probably not in the most friendly manner.
After that incident, we invited him round for dinner on father's day but before he would come said he had to see my husband on his own to talk first, which they did. He basically said it was rude of us to tell him not to turn up unannounced. I don't really know what happened at their lunch but he came for father's day dinner and then we didn't hear from him for ages after, he just didn't respond to any messages etc. so we mostly gave up.
Come Christmas, we tried to get him to come round again and after weeks of his ignoring us he finally responded that he wouldn't see us because he had people who actually cared about him who he "does't have to make an appointment to see." Along with a whole slew of emails about us being under the control of his ex, who is evil incarnate, etc.
Well, the boy's birthday was yesterday so I thought I would try one last time. I only sent one email inviting him to see us (I as not going to chase him down again like we had to at Christmas). I suggested a few times that were good for us. He replied that it would be good to see us but that he couldn't do the suggested times, and suggested some of his own. When I said that unfortunately we couldn't do the two days he suggested but we were free all but one other night for the rest of the month, he completely freaked out. He said that we were trying to be manipulating and controlling by not cancelling whatever was going on to see him those days, that we were being 'controlled' by his ex to try to do him harm, all sorts of kind of really out-there things.
He sent me a whole slew of emails and in the end it comes down to this: Either we do what he wants and let him stop in unannounced whenever he wants or he will be convinced that we are under his ex's "control".
So, what would you do? There is a BIG part of me that just wants to wash my hands of him, but I feel like that would be doing my son a disservice. I really, really do not like the idea of him turning up when my husband is out. Do you think we were out of line in asking for advance notice of his coming? Should we take it back?
It is super frustrating because I know that my parents would jump at the opportunity to see the boy on holidys/his birthday/etc. Even though we would ask them not to turn up unannounced either!
