NC for this as a handful of people know my regular username and knows me in RL.
I've been with my DP for 5 years, been living together for 3. I get on great with DP's DM, been invited to her house regularly and always made to feel very welcome, been invited to family events, holidays with them and she always buys myself and my 3 DC (from previous relationship) wonderful gifts for xmas and birthdays and even when she's been away on holiday, we've had great conversations together and she's just a genuinely caring, loving person and mother. But she has never set foot in the home I share with her son.
She's been invited on several occasions and I think I've always made it very clear she is always welcomed. She only lives a 50 minute drive away and is a very confident driver so I know that's not the issue.
A few months back DP asked her to drop off some important documents she'd found that belonged to him. He told her I was home all day and I waited for her to call round but instead of knocking of even just walking in she posted them through the letter box.
Just last month we were having a party, we sent her a lovely message telling how much we would love to have her company and she never came which upset me a little.
I've asked DP to have a word and ask why, but he wont as he doesn't want to to upset and pressure her. He says she just likes her own company and prefers to be at home which I can understand but at the same time, we've been in this house for 3 years! I can't imagine not visiting my DC in their homes.
His DF has visited us on several occasions (divorced from his DM) and lives 6 hours away so I know DP isn't keeping his parents away.
My friends think I should count my blessings as their MIL's are always 'round their homes, interfering. AIBU for thinking its strange and should I say something or should I just accept this what she wants?
