My Boyfriend Dumped Me After He Became Rich

I dated a guy for a year and last year he broke up with
me, saying he wants to get baptized. I was shocked and
heartbroken when he said that to me, because this was
a guy I suffered with when he had nothing. I was there
for him. I loved this guy to pieces before he became
rich.
It's been about 5 months since we separated. In those
months I missed him so much, was really thinking that
he would call me and tell me that he wants me back. My
birthday passed, no call from him so I gave up hope of
him ever coming back to me or we just being friends.
I was shocked when he called me Dec 20th and was like
''I'm sorry I forgot your birthday. My conscience has
been judging me for not calling you.''. I said no problem
it's okay. Since that day, he hasn't called.
Not until this week, he called and said he wants to see
me, that he's very ill, that there's no one to take care of
him. I told him I was not coming. He kept on disturbing
me so I decided to go see him...
When I got to his place I found out that he wasn't really
sick like he said. So we got talking. He told me he wants
me back, that my type is rare, that he has tried
searching for someone like me but to no avail. He kept
on apologizing to me and said that he has changed. That
he knows he made a mistake, that he's only human.To
cut the long story short, he said he wants us back
together. He wants us to plan our future as one again.
Before I left his place I made it clear to him that I am
never going back to him.
The thing I don't understand is that whenever I pray for
a better person, it's him I see in my dreams. If I don't
see him in my dreams, he calls my phone. I'm confused,
even though my heart still wants him back, I don't know
what to do.
Some of my friends have told me not to go back to him
and some say if you still love him go back but give him a
tough time. I forgot to mention - this guy still holds on
to a love note I wrote him while we were still together.
He showed it to me when I went to see him. I was
surprised thinking he has long torn it.
Please I need your advice and opinions. Thanks.
