Ok, tell me if I’m being totally unreasonable.
DP & I have been together almost 2 years, we have been living together the last 8 months, his son lives with us 3/4nights a week, (3 nights one, 4 nights the other). DP and his ex split when son was 1.5 years old, so have been separated 6.5 years. I have an ok relationship with his ex. DP and ex only get on for child’s sake. I have been completely reasonable and tried to make their relationship as co-parents as stable as possible, despite a new person joining their team. We have a relationship where we will often have 5/10 minute chats based around DP son, just her and I. I’m not saying it’s been easy to get to this point in our relationship but I was under the impression we were very amicable.
Fast forward to today, DSS birthday party at mine & DP house. (He had a celebration at his mums where he just wanted a sleepover with a friend) He asked for a party too, his mum said she wasn’t having any part of the party as she hadn’t planned it, despite me asking if she wanted to help, she insisted she was happy doing separate things for DSS. 10 kids- friends from school and cousins, then adult family members (aunts, uncles, grandparents) and his mum. DP ex (child’s mum) turns up with one of her friends and completely ignores me, goes into the garden to DP family, speaks to them fine, I go out to the garden to sit and she turns away from me, blanks me the whole time as if I was invisible then disappeared. I went in to the kitchen to make teas and DP is with his father talking, I look out to the hallway and DP ex is walking down the stairs, she had been upstairs in the house, (?!) Even if she needed to use the loo she could have waited as there is one downstairs. I then noticed this wasn’t the first time she’d been upstairs, she was up and down about 3 times during the party (DP was downstairs in case anyone is thinking hanky panky and kids were outside playing). I didn’t question it, let it slide. She was still ignoring me, DP asked if I could do some party games so I did them and I went back into kitchen and she is making everyone tea, asking DP where things are etc. I said to DP shall we all sing happy birthday and cut cake before kids go. I get kids sitting together to sing, I went back in to the kitchen and there she is putting the candles on the cake with DP and being absolutely fine with him- despite me telling him she’s ignoring me.
When talking to DP she said as doing in a sweet sort of way, like butter wouldn’t melt, that she never talks to him in, they barely speak on pick up/drop off.
Cake done- she asks for a slice for her young nephew, I explain that we’re cutting the cake for party bags and can he wait until then. She ignored me and went “DP can you cut a slice for ‘said child’” I just looked at her?! And said again, cake is being cut to go into party bags as the kids are leaving in 3 minutes, DP agreed.
I’m quite frankly pissed off:
1 that she ignored me the whole day, but made sure she thanked me in front of DP family at the end of the party
2 about the going upstairs, which I am extremely confused about
3 every time I wasn’t in the room she was, eg, making people tea/ doing candles on the cake/ asking why this had or hadn’t been done
I do believe in moving forward I’m going to keep it brief or completely ignore her- she made her feelings very clear today in front of his family members and made me very uncomfortable in my own home.
However, I don’t think this would benefit anyone.
Anyway I’m just a little confused about everything today, I feel like I need a little rant or your opinions. Sorry it’s long, if you got to the bottom well done.
