Needing to vent/complain a little ..

I have ZERO friends because they all dislike my boyfriend.

All with good reason but I wish I had people to talk to, or even hang out with...

We have 2 kids together and our relationship isn’t that great. -going on 6 years-

***(yes I know I should just leave him for the sake of the kids but We depend on him financially)***

He is very flirty with his co workers and every time I mention something he says I’m insecure..

Or that just because I’m 25 I “need to stop being a little girl and grow up and stop being insecure”

I just had our second child 8 months ago. I’m no longer a little size 3. My stomach is saggy, I have back rolls. I don’t feel “beautiful”. I’m never told I am . I try my best to still dress up and do my makeup but even then I don’t feel the way I used to. He doesn’t hold me like he used to, he hardly kisses me . When we have sex he doesn’t look at me.. he doesn’t touch me.. yes he initiates sex most of the time but I feel as if I’m just a body he uses for release.

I wish I was reassured that he “loves me” or that he isn’t doing anything behind my back because he doesn’t find me attractive ..

I can’t talk to him about any of it because he says I’m being insecure and he “won’t put up with it much longer” ...
