Is it normal a guy wants to give girls money?

i'm in a weird relationship with someone
someone that i'm living with in a very same room, cause i had no job and no place to stay then. so he wanted to help so he let me stay. he spent all the money for me cause i had no job i had some money but he won't let me spend it.(later i found out he told his friends that i'm living off of him.), even after i got a job i forced to stay cause i love him, but he really hated me staying with him,he just let me stay cause he couldn't just kick someone out on a street.

the thing is we've been sleeping together(i was always forced on him.)it is obvious he has no feelings for me, but i do... he is seeing other girl(i have seen her she's a lot older than me and not pretty at all.just boring. i'm much better looking than her i dare say she's not one bit attractive than i am) and flirt with many girls with texts behind my back then i get to find out i get hurt but he's keep seeing them. probably because he's in to them. yet we're still sleeping together and he treats me really bad.

now i'll be leaving to different country and we may never see each other again,

suddenly he wants to give me money, not a gift , just cash.
(it was my birthday few days ago i didn't get any gift.he researched days just to pick a cake, made an dinner reservation at the restaurant, and wrote a card for the girl he is seeing(and who knows maybe he had gift for her too something small that i couldn't see he was carrying,for my B-day he got me the same kind of cake for me no effort whatsoever that's all he done for me.)
he wanted to give me money to help with my traveling expenses(it would help but i don't necessarily need it and he knows that too.),

then he wants to give me money so i can go out and party. (he used to hate me go out party cause i didn't have a job although i didn't pay for it. all my friends did.)i wasn't going to, he actually suggested i should go out and party.
i asked why would you do that, said it will be the last Saturday on this country for me.

but the thing is it will be the same night we're gonna go out and have dinner for the last time as well.(and it was suppose to be make up for my birthday)i asked what about the dinner then he goes "dinner doesn't last all night, you can go after" i got mad i asked him how am i gonna get home since i don't have car, and there will be no public transportation at that time.
he says "you can stay out all night."(he means, you can crash any strange guys house and do whatever)

and also when we was out yesterday and was going to grab something to eat , i didn't eat cause i didn't want to eat there. then he was try to giving me twenty dollars so i can go eat something while he was finishing his meal.

he's been saying the reason is cause i have no job now,no income and i seem i don't want to spend money.

i don't think that is true(given he's always been giving excuses and lies for me.)

thanks for reading such a long text, i talked to much out of jealousy, anyways

what would be the reason of this guy keep trying to give me money?( i haven't accepted any, of course.)
i'm literally dying to know.
