This was always a hard one for me.

i am a truly nice guy, and want to give everyone a second chance.

Believed in the bullshit, "you shouldn't judge".

But, if you are going to be in a relationship with a person, then you should look at what kind of person they are. And their past actions are very good indicator.

Unfortunately 99% of the answers to the question of "why are you a single mother" lead to a conclusion that this person is not a good person for a long term relationship.

...and you will always be 4th place in her life... or lower.
