I think it’s selfish to remain in a relationship with the Father or Mother of your child just because you don’t have the “balls” to tell your child you’re no longer in love.
I get it, that shit sucks! No kids wants to deal with their parents separating, but you know what? The sooner you end things, the better.
Kids are smart, they pick things up. They pick up the good and bad vibes in life, if you’re not happy they’ll know and it’ll only hurt them more in the future knowing you stayed together because of them. They will blame themselves and honestly that’s not something you should ever want for your kid.
It’s just my opinion I guess but, I’m glad my parents divorced and separated before I was old enough to understand what was truly happening. Two homes are way better than one broken home.
