That's tough, ay at least the broad stay in the gym lol. And look fuu, even with all that, a nikka would still be wrong to have that be the sole reason he dip on his babymoms and she's making herself a true effort to stay loyal to whoever breh(or prolly creh, she look like the type lol) is....you just gotta eat that. And work with her to the best of your abilities. Cuz that's "nature's" way of keeping the woman humble. They lose some of that glow and luster for a reason once they have kids....so they can focus on what they were created to be, wives and mothers. And not still out here thotting it up, tryna court the attention they've already got at home with their supposed family. Yeah I said it.
And imo, if u have kids with a bytch that woman is your wife in spirit/emotionally at the very least. I don't care what this society says constitutes a marriage...One night stands included too . Be more responsible before the fact is all I can say, cuz if ol boy ditched girl in OP off the strength of just the weight gain after a baby, and you already know she's a gym rat, yeah that's pretty wack man .
