long story short i broke up with my ex 6months ago its been hard but im moving on. happy and realise its for the best after 3.5years of messing about on off relationship i know he can't give me what i want and commit. we are still friends were friends for 15 years before getting together since school. he wants to have contact with my ds who is 4. thing is i don't know if i should let it continue because i can't see it being a long term thing. he has a new woman in his life and is not being honest with her about the situation i can just see the shit hitting the fan before long and that will be it. am i worrying too much or should i let them be friends and hope for the best. i don't want ds getting hurt/ let down. just don't know what to do for the best
