Children’s dad

[Jilly43]

I’ve known my children’s dad for 15 years, we’ve been seperate for 4. He’s had girlfriends but always comes back to me for help or wants me when they spilt up, he turns nice and then evil. I let him stay at my house for a few months and we was sleeping together after all them years, told me all lies clearly to then leave again with someone else and turns nasty on me? I don’t want to help or be there for him anymore, we’ve done this before and he comes back and this time I want it to end for good for my own mental health, he’s not a nice person and is currently seeming to change which I know the real him so he’s love bombing his new girlfriend, I currently have him blocked on my end but how do I deal with this?

Counselling for you to work through this, and kindly I mean to also figure out why you allow yourself to be treated like this.
Write down your boundaries, don't tell him what they are but make sure you stick to them.
Co parenting app only discussing the children and nothing else.
You know his pattern, don't ever give him another inch because he will take a mile.
Remember, he doesn't actually respect or care for you. He uses you. Now is the time to show your children about boundaries and putting yourself first.
