4 months in and struggling again

[PesothePenguin]

Hi
I split with my ExP earlier on this year. We have a 3 year old DS who lives with me though he stays at his dads 2 nights a week.
He cheated on me and dumped me. I was and still am devastated.
I moved house to be nearer my family and 1 month after my move my mum suddenly passed away.
I have been struggling to say the least. My ExP has been supportive and we were friendly and things were getting better for me despite the utter loneliness.
Last weekend however i found out he has been seeing someone new and i am struggling to deal with it. I absolutely cannot stop thinking about him. My heart feels broken all over again.
Deep down i guess i always hoped to get back together even though he treated me like shit and verbally abused me. One comment from last summer stills haunts me when he said 'fuck off and have a heart attack and die you fat cunt' - charming eh?
I KNOW i am better off without him and in time hopefully will meet someone new.
What I can't seem to do though is to stop constantly thinking about him, our past and the loss of my family unit.
I never wanted my DS to come from a broken home as I did and had a shit relationship with my DF.
We have been doing things as a family including a recent weekend to Peppa Pig World for our DS. I am trying not to contact him since I found out about his new GF as he basically doesn't give a shit about me but when and how does my heart heal when i have to see him twice a week?
Any tips out there?

I would seriously stop all family events/outings. Do not go out 'as a family' if you can help it or you'll torture yourself with this. And keep the drop off/pick up as short as possible. Same with all contact during the week about arrangements/times etc.

Op...he is the cunt here. Of the highest order. I would pity his new gf. Id stop such outings and tell him to fuck right off.

Yep, reduce contact with him to as little as possible. Can you do drop offs on the doorstep and not allow him in to the house?

As the other posters have said, you do need to set boundaries. You really shouldn't do family outings. It will be confusing for your DS.

You are all quite right. I need to set boundaries. I'm so sad though that my DS won't be spending time with his mummy and daddy together anymore. I hate my ExP for that. My DS loves us all being together but I just can't do it anymore. It breaks my heart.
Thanks all x

I agree. Family days out end when the family ends. You do need to have as little contact with him as possible in order to move on. It will be easier for D'S in the long run
