Why women stay with a jerk got them pregnant then call the nice guy and tell him they are sorry to reject him?

is like this she rejects a truly honest loving man by saying unquote" you're such a nice guy i don't want to ruin our friendship" unquote then they have sex with a bad boy, abusive jerks and sure some of us nice guys may not fight but if he must he'll fight anyone to protect people who he loves and care about to defend others and defend himself if necessary but some reason some women reason they see that as a weakness what's going on here everybody if you do the math you women cry about nice guys but you chase him off and you let him date and marry a foreign women and/or older women because you don't know how to treat nice guys right if you guys got a take or got something you want to disagree or agree feel free so far looks like nice guys do finish last because they don't want to get know us and they act like they love it when us nice guys ignore them please clue me in on what's going on here with women's Society today they say they want a nice guy but they run away if he is truly nice with a loving heart and they stay with a bad boy, a abusive jerk then when they get pregnant by them or after she had sex with him they want to know where is the nice guy newsflash they chase off and we date and marry a foreign woman, and/or older woman any advice or your take on this would help thanks have a good day may god and Jesus be with you
