Ahhh. This step-parenting lark is driving me bonkers! Okay so dp and I were getting along great. Complete u-turn from the non-supportive tight man from a few weeks/months ago. Unfortunately dp had an accident and has been in hospital since saturday (nasty fracture and op) Terribly missing him and its really hard to keep the routine (even though I am more than capable) just not having him there (sad) Dss who lives with us had actually been quite good. Looking after dcs while i go and visit and drop him stuff. Then me and dss saw dp last night before op and wished him well and went after he was settled after op. (sorry long winded but I will get there) Naturally all our friends callling wanting to visit etc... But this morning, his son of 24 and girlfriend in tow just turns up opens the front door without ringing and proceeds to take over the household?! Did not call or contact to say he was coming, expected dinner and lodgings for the night. Then dss (who had been okay up till now) comes downstairs, invites girlfriend round and they all proceed (four adults) to take over the living room !!! AHHH They walked round like they owned the place (even dss girlfreind who refuses to even speak to me) and does not have the courtesy to even consult me in my own home!!! I drew the line when after I had returned with dcs from school(7 people in front room by now) dss proceeded to snog his girlfriend!!! I politely asked him to not do that in others company and i got a snide remark back. Dss girlfriend sat on the arm of my new leather sofa which I politely asked her not to sit on the arm and she does not even batter an eyelid ! (new expensive leather sofa for which dp and i jointly purchased) I know it may seem maybe I am just oversensitive, but I am sick of everyone walking over me and doing as they feel as if its a sodding hotel. Like my dp is going to want a house full of people when he gets home (his own comments) . I think its inconsiderate when his son just turns up as and when no prior calling and bulldozing into our lives. Our plans are often ransacked on the weekends when this happens. I have asked them to call to let us know so I can at least arrange bedrooms and get enough food in ( I have no problem him and partner visiting but would like to know). All I wanted to do was have a peaceful day revising whilst the kids were at school and try to cluck for when my dp is home. Instead I had my living room turned into a playgrounds and four adults ignore me. AIBU ?
