Just a rant

I'm pretty sure it's my depression talking or my insecurities idk. But I just feel so down on myself anymore. Me and my man took a break at the end of December into January and he slept with someone else and idk I just feel so ugly and like he's just gonna leave or cheat idk if he would cheat but he's left me multiple times for a day up to a week before and we always got back together but idk. I'm just tired of feeling down on myself. I know I'm not the prettiest girl out there but id like my man to make me feel like the most beautiful women in his life but he doesn't and I truly don't think it'll ever happen... Idk man.
