Can you ever be friends with you EX?

[Oakleaf40]

My husband and I are separating after 19 years together, His decision. We have two teenage children and a business together. We haven't sorted anything out regarding the business or moving out etc. I know this isn't going to be plain sailing its difficult enough to deal with him wanting to separate but he has this attitude of we can be best friends ? lets be friends!!
19 years together wants to separate and be best friends? Am I going crazy!! All I want to do right now is scream, how can he think that I am just going to say yeah sure lets end our marriage and be best buddies!!!

I'm friendly with my ex (DS's father), wouldn't say we're "friends" as we don't socialise together but we get on well. He has a long term partner who I get on with and I'm not sad about it at all.

Its all so tricky, he keeps saying let's be best friends and who knows what the future could be like. Says he will fully support me with money etc not sure I'm totally believing it all. Im just trying to get through each day. I have had a bad few days bit coming on here and talking really helps. Xx thank you all so much.

Yes. I'm good friends (in a couple of cases, very good friends) with a few of my exes ... but in every instance we needed to break completely first, and sometimes for a few years.
