really sorry to hear ur going thru this hun, its hard as hell. but u will pick urself up at some stage, theres no time limit on it, but u will get there.
My husband told me when i was 6 weeks preg that he didnt love me anymore, ( i later found out there was someone else) he put me outta our home and shut my business down. But i picked myself back up and am trying to make a fresh start.
I got a new house (rented as i cant get a mortgage) and im now working from home. Yes my ex still f*cks me off and trys to mess things up for me but i just try and wave it away.
Talk to ur mum, see what ur options are. Ul be entitled to housing benefit cause ur not wokring, and have child. Way up the pros and cons of staying there, maybe moving back near family would be better. Keep people close and get as much support as possible.
The girls on here are fab and have got me thru some times. If u need anything just PM me, Il try give u as much info as possible hun, or even just listen
Hope ur ok x
