So I was minding my own business enjoying pregnancy today. When I decided to cook dinner I was talking to my s.o about deleteing dating profile off dating sites. I accidentally called his brother on Duo. Hanging up I let him know and his brother called back. Then he told him to just call him on the phone. So when his brother called him he walked off to come back with some news. His baby mother was trying to get in touch with him. He took the call. He invited me to listen in. So she told him he has to get the kids a while. So I'm thinking a weekend here and there. Or while they out of school over summer. But she said A YEAR 365 DAYS LIKE EVERYDAY OF THE WEEK. Lets make this clear OUR baby daddy doesnt have a house he stays with me. OUR BABY DADDY is unemployed at the moment I'm BUYING. I STAY IN A TWO BEDROOM APARTMENT THAT I SHARE WITH MY BROTHER. So not to be mean there's no room. I dont mind his kids coming. I ASKED to speak to her. She got smart with me told me she's only leaving her kids with her BABY DADDY. WHEN HE CANT AFFORD NOTHING I WILL BE RESPONSIBLE UNTIL HE FIND A JOB. ADVICE..

I DON'T WHAT TO SAY? MY S.O HAS A ATTITUDE WITH ME BECAUSE WE DONT HAVE SPACE AND I KEEP TELLING HIM HE STRESSING ME OUT. SINCE WE BEEN TOGETHER I'VE PUT UP WITH HIS DRAMA FILLED LIFE.
