My DP's wife left him years ago for another man. Their three teenagers stayed with my DP. Then I met DP and we've been together for some years and have two DCs.
Recently one of my DP's children became ill (walking wounded). She's now adult but her mum still wants to see her as much as possible. Ex-wife's new man doesn't like her family visiting her at their home.
Since she works full time, I suggested she feel free to visit any evening plus weekends as long as she gives DP a quick call first. I'm not keen on her being around when DP is out because she is unpredictable & prone to hissy fits.
All seemed happy with this until she started yelling at me in the street, saying I was keeping her from her child. I hate scenes so retreated and let DP deal with it.
But am I being unreasonable? I just don't want her in the house when I'm in the shower or getting the little ones out in the morning.
