my boyfriend was emotionally invested with another female for a whole year. eventually around the end of the summer they began hanging out and it was now physical. he swore to God and on his families lives multiple times to me that he never would cheat or do anything of that matter. i didn't find out till around november about it all. i took him back. idk if it continued or not but it honestly made things worse bc i couldn't get over it and we never had trust. everything was just a big mess so about three weeks ago i said i wanted to really call it quits. he's been sending me long paragraphs, buying me flowers and stuffed animals, calling me almost every night crying asking for another chance. but i've given him multiple chances and it's always the same. how can i know it will be different this time. i won't trust him but he seems sincerely sorry. i don't want to get hurt again and i do care about him a lot. it's just hard and idk what to do anymore. help please if you can ...
