He isn’t accepting it’s over and it’s giving me anxiety

[StressLevel100]

I haven’t lived with my ex for 3 months, we have a 11 month old dc together so hence there is still some contact.

I’ve told him 3 times now that it’s over and he won’t accept it. Tells me we need to talk about it, that we need to be in agreement, that he doesn’t want our DD having single parents or growing up too close to my family, that all he has ever done is provide for me and DD (since leaving he has barely given maintenance esp when he is a high earner). I’m just at the point where he is causing me so much anxiety and really not respecting my boundaries at all. What can I do to get him to give me some space?

No, you only need to be in agreement if you want to stay together and work on your relationship. That takes two.

Breaking up takes one. You both have to want to be together or no relationship.

Tell him it's over. Be firm. And get legal advice immediately.

Go to CMS for maintenance!!!

Do not engage with him on anything other than the child. Simply "we are over. I will no longer be discussing anything other than our child with you". If he carries on, walk away/hang up the phone don't reply whenever he broaches the subject.

Never let him into your home. You don't get him to give you space, you TAKE your space. Don't try to reach compromise with him because every inch you give, he'll just want to turn into a mile.

All easier said than done of course :/
