Have you ever be cheated on ?

Have you ever been cheated on , and felt so stupid for ever giving that person your all . I know it’s stupid but I feel like it’s my fault like I’m not enough I feel humiliated and resentful , the worst part is I don’t even feel resentful towards him... I resent myself . I resent myself for allowing this to happen . For ever allowing him to get close for believing his stupid fake love talk . I don’t know what to do with myself i have no one to talk to and it’s just so much harder .
