if he feels he does not want to marry the woman, its ok.
All he needs is to organize for child support through an arbitrator e.g parents or village elders.
If thats not possible he can organise thru childrens department or children's court.
My advice is for him to initiate this as opposed to wait till the woman has received orders to get his 250k from his 8k salo.
If he lets the woman initiate this and she ends up wanting to settle some scores, he will end up Mr.Moi style with 250k per month payments yet he earns 8k per month.
If he controls the case, the magistrates/judges will be fair and will award a fair judgement to all parties.
