Stay or leave

I'm so lost. I've done it all and I still feel lost.

Last night I was puking and my SO went to go pick up his daughter from a friend's house. Definitely needed to happen. So he said he'd be right back..

But he wasn't. He went to his ex's house after contacting her about something stupid he still had of hers. Like an excuse to see her.

I called him right as he got there to ask when he would be home because he should've been by then. Right after puking twice. (Mind you later he tried to poke hole in my time line like I was the one who did something wrong here) and he said he wasn't coming home. Until after he dropped it off. Like fuck you.

Then 20 minutes later he comes home and starts taking care of me like he didn't do anything.

And told his daughter who calls me mom i was being controlling. I haven't felt good in 3 days. Yes I'm definitely doing this on purpose and want you here where you said you were going to be.

Like he should've been back 20 minutes before not then. He stayed home from work to take care of me supposedly. Like wtf. Then goes and does that....

I love him. But this isn't the first time he has done something like this.

I'm. So. Lost.

My boundaries are broken all the time. And I don't feel respected ever. So why stay. I don't know why I do this to myself.
