Can anyone who's split up form there partner after having a baby tell me how to work round this? We are still living together at the moment but it's not working he won't accept we are over and doesn't want to separate albie from either us which is understandable BUT I do eventually want him to move out if this is over for good but how do we work around this? Does it affect a child who's only 1? I come from

A broken home and it fucked me up
