How would you feel if you find out that your boyfriend cheated on his three last girlfriend with his daughters mom? They broke up because she cheated on him with another guy but they never stopped having sex even though her and that other guy have a daughter together and live together. They have sex for three year straight from 2016 to 2019. Would you worry that he might do the same to you, even though he swears that he isn’t going to cheat on you with anyone? Would you have a woman to woman talk with her? I know that my boyfriend is the one that’s supposed to be faithful to me but since she said that she wants to have a respectful relationship with me, I feel like I should have an honest conversation with her. Do you guys think that’s a good idea? We have a one year old son together and I found out about what they were doing on May 12th a day before our sons first birthday.
