Why do you have to go back to your mom's? You have a job now? Can't you keep your job and get a room in an apartment with roommates?
This is time to work on yourself, your own self esteem. Living with a lying cheating bitch just because you don't want to sleep alone is pretty sad. You'll find someone better when you learn to love yourself.
She's playing you. You're worth more than that.
Love withers under constraint; its very essence is liberty. It is compatible neither with envy, jealousy or fear. It is there most pure, perfect and unlimited when its votaries live in confidence, equality and unreserve. -- Shelley
