Lost and confused.

My so of 5 years left, we had been distant and he said he was thinking of leaving for months but didn’t because I’m his only place to live. He is now living in his car. He decided to cut it off and said that now he’s with another girl whom knew we were together and they just started this weekend to be a thing, he says he is so happy. I’m so hurt and lost I gave him everything. I have put up with family drama. Him being on probation, and heartbreak. We lived together since we were young, now it’s me and my dog and I feel hurt. He was my first one everything .I’ve never felt pain this bad...
