I think my mum is sleeping with my ex 😫

I’m going to try and explain this all as clearly as I possibly can, but these problems have been stuck inside my brain for so long and Ive held my peace for such a long time I find it difficult to know how to speak up.

I was with my partner for 4 years. We lived together for 3 years and have an 18 month old child together. In July last year we decided to move back to my parents house together to save a bit of money.

My parents really liked my partner, he was like my Dad’s bestie, and my mum just adored him. Let’s fast forward a couple of months and my parents split up (they stayed living in the same house, dad just started sleeping on the couch)

My mum and my partner started getting closer and closer. Drunk emotional chats, hugging and crying together, joking together and staying up late together etc, and it slowly started to get on my nerves a little bit, how close they were. My mum even admitted to me a few times that she had a crush on him.

Then I broke up with my partner, for many many reasons. He was really upset and bitter at first, that’s when my mum started “supporting him” and spending lots of time going for drinks with him to help him get over the breakup. At the time I didn’t care because I was just trying to focus on my son and my happiness.

Now lets fast forward to now. He has moved out and is staying with a friend. My mum suddenly says she can’t stand staying in this house with my dad and she moves out too, to stay at her uncles house. She’s brought another house but can’t move in just yet, but when she does, my ex is going with her.

My whole family are in uproar about this, especially my dad who feels like he’s been stabbed in the back by someone who’s meant to be his friend. But neither my mum nor my ex care about what anyone else says and they insist that they’re just “best friends”

Well now the secrets have started. I only communicate with him about our child, but when it comes to my mum, me and her are really close. Last week I asked her if she was staying home on a specific night or would she be at her uncles. She said “no I’m definitely staying out that night.” When I asked her what she’s doing she wouldn’t tell me, all she said was that shes just “booked something” and “never mind what or where.” Then I asked her if my ex is coming with her and she sheepishly said yes. I told her I don’t deserve this secretive behaviour and the sneaking around is making it look really dodgy. She said it’s only a little 2 bed place so they can just chill and have some drinks.

Then tonight, while she was at her uncles, I drove past the house to see if my ex’s car would be there. I just had a gut feeling about it. I drove past and saw her car, then yep, there was his car too! So he’s actually staying at her uncles house with her tonight! I pulled over and rung her, acting all normal. She was really flustered and overcompensating her friendliness with me.. a very guilty sign in my eyes. Anyway she told me she’s watching a film and she’s alone. I didn’t tell her that I’ve just driven past.

I’ve asked her if shes in love with him and her answer was simply “I haven’t really thought about it.” And I’ve also told her that he is my ex, the father of my child and nothing can ever happen between them two, her answer was “yeah but you don’t want him.”

This is a lot for me to process and I don’t know what my next move is. I feel totally and utterly disrespected and betrayed by my own mother. They shouldn’t be hanging around together and certainly shouldnt be moving in together. I’ve voiced my concerns, my whole family have, and they simply do not care.

I must add for the record that I’m soon to be moving into a little place on my own with my son, again that’s another waiting game but hopefully in the next month.
