This is complicated so I’ll try and make it brief and please no hate I’m genuinely confused and trying to do the best by everyone.
DP lives with me and my two boys 12 & 15 and he has a DD age 19 at university, she comes home to us in holidays etc . I honestly feel love towards her as do the boys, known her since 14 etc we do nice things together as a blended family , she’s fully integrated into my huge family etc.
DP and DSD ( call her that for now) are incredibly close, they speak daily , and had a few years living together when her parents split before they moved in with us ( her mum is a doctor and works mad hours)
She gets on well with her mum but she’s not around much , has new partner and new child . I’m very aware of this and make sure she has plenty of time with her Dad and always feels completely welcome here. I actually love her being here.
BUT I feel sometimes that their relationship is a bit much emotionally and sometimes physically too (NOT sexually obviously) but sometimes very cuddly - she sits on his lap - they are both tall - she is 5.9 and he is 6.4 so sometimes it looks a bit strange . They hold hands sometimes whilst we’re out. She is very emotional and calls him sometimes 5/6 times a day . She fills him in on every thing happening at uni and runs all decisions by him. She sometimes gets a bit upset if we are alone and kind of plays him off against me wants to be alone with him a lot and says things like ‘ I need some time alone with my Dad ‘ quite regularity for dinners out etc but in quite a dramatic way rather than just them hanging out . Ira hard to explain but my sisters ( all have kids) have also noticed it they love her but feel likes it a bit much.
Its hard but we have a lovely relationship , she seems to love being here but I feel like she’s more confident and even happier when he’s not around, or when she is making decisions without him - he works away sometimes and she’s here with me and the boys so it makes me feel like the boundaries with them are a bit blurred. The physical really bothers me - once someone thought she was his girlfriend when we were out and it mortified me - maybe I’m just jealous but I’m also just a bit creeped out to be honest . I don’t want it to cause a wedge between us so I haven’t said anything I have to be really delicate. Don’t know what to do!
