The parents were probably on fertility drugs before conception. And they tried abortin wit drugs but wen d damn baby wldnt die, they decide to leave him.
Hence, d malformation.
*my thoughts*

@OP: save urself d stress, most ladies won't listen. They'll rather fall into same mistake and regret it later.
Everyone needs experience. Abeg, allow them

It all depends. Has he been callin u regularly b4 but suddenly stopped? If that's d case, then there is need to worry.

I av a similar problem with my babe. She's been callin b4 but all of a sudden , she changed. Even wen I call her sometimes, she'll quickly answer and call and tell me she'll call me back and doesn't until 2 or 3hours later. U see what we are talkin about?

We humans worry about a partner cos we love and care. But wen we get wearied out, we just av to stop caring and kp our fingers crossed and watch tins happen.

@op, put ur mind @ rest. If he's urs, he's surely goin nowwhere but if not, allow him to go. Someone faaaaar better is about comin ur way
