Every freaking relationship I've been in I've been nothing but faithful, loving, and the best damn girlfriend to my SO. But they just throw that all away and CHEAT on me. Then, when I finally think I've found "the one," he proposes, we get engaged, we conceived a baby and guess what?! He cheats on me.... Not with one woman, but multiple. I don't even know what to do anymore. Feeling so lost and down....
