Are you sure he is not a fake profile? I was emotionally duped by a Nigerian dating scammer a while back, He had copied and pasted another man's photo, was a widower, educated (Masters)and in engineering. He supposedly lived in the same city as me, with his 5 year old daughter.
Then.... he got a contract which would involve three weeks in West Africa. Lo and behold whilst there he encountered problems with customs and hadn't budgeted for the additional expense...
I wasn't surprised by that time, when he asked me to help him with "only £900" via Western Union!
Of course he didn't get a penny, and I reported him to the dating site.
Googling is a very helpful tool if you have any doubts about someone on a dating site!
He had quite an unusual written profile, very distinct. I copied and pasted the first sentence, googled it and lo and behold the same "man" same picture, same name, just slightly changed details, was on an Australian dating site too! Only this time he lived in Sydney!
I know there are genuine men on these sites but sadly there are lyers, losers and also criminals who are based in Nigeria using fake profiles. So I say you should google away!
Good luck.
