When you break up with someone that you have a child with because they were cheating on you, why go back?

I am back with my sons father but now I have a six month old daughter by someone else and everytime I see my daughters dad, some of those old feelings come back. My sons dad and I live 10 hours away from each other but my son is five and we have been on and off several times and this time he asked me to marry him and I want to and move away but, I'm concerned about what my daughters dad will think and some days I want him back and maybe its out of lust instead of love but I don't know how to tell the two apart when I love him and the love we made was sensual.When you break up with someone that you have a child with because they were cheating on you, why go back?
MY SISTER IS IN THE SAME PREDICAMENT. HE AND HER EX BOYFRIEND WAS TOGETHER FOR 4 YEARS BEFORE THEY HAD THEIR FIRST CHILD(MY NEPHEW). THEY BROKE IT OFF AFTER HE WAS ABOUT 8 MONTHS(04). THEN SHE JUST HAD MY 3 MONTH OLD NIECE IN DECEMBER( WITH ANOTHER BOYFRIEND) AND THEY'VE BEEN TOGETHER FOR ABOUT A YEAR AND A HALF. SHE STILL HAVE FEELINGS FOR MY NEPHEW'S FATHER THOUGH. MAYBE YOU REALLY WANT TO BE WITH HIM AND HIM WITH YOU BUT YOU DON'T WANT TO HURT YOUR DAUGHTERS FATHER FEELINGS OR MAYBE ITS LUST.When you break up with someone that you have a child with because they were cheating on you, why go back?
everybody cheats. You'd do it yourself. don't be a hypocrite. You want your ex for his wallet. You want your new guy for your vagina. You have two kids. Start thinking of them for a change.
maybe you should talk to both of them and see what they think i mean what's worst than putting everthing out in the openning you shouldn't keep everthing inside at least you will know what they are thinking. good luck
Well it seems like you only want to marry him because you want that stability for your child...you need to give yourself some time before jumping in the this...it may be more wanting stability that love.
Hey, you are a mother of tow kids. that's OK! but you have your own life too! think about what is the best thing for your own, and then decide. you've gotto live as much as your kids do.
