a trip on memory lane 😩.

in 2016 this guy and i was talking we broke up in late 2017. when we was going out he would say hurtful things to me and i found out he was cheating on me. so , i broke up with him and he tried to come back but i told him that i’m done with him. now it’s 2018 and i’m soo happy with my life. so now me and this guy is going out and everything he says or do reminds me of my ex. i don’t want this to ruin our relationship because i really do have strong feelings for him. what should i do ? should i confront him about it or just try to ignore it ? everything’s going fine but i’m just scared of the fact everything he does reminds me of my ex 😭🤦🏼‍♀️.
