So im a first time mother (kinda)

With an almost 1 year old...

My partner has an almost 5 year old son to his ex..

I am very lonely and have no friends, I've tried making mom friends and joining mothers group but no one wants me around.

I'm not sure if it's legitimately because they don't want me around or because my partners ex who has alot of friends and very well know has talked shit about me.

We used to be bestfriends, but lately she's taken our time away from their son and won't let us see him.

And I honestly feel she's talked bad about me to the young mothers.

I don't know what to do, I'm so lonely and I'm at breaking point.
