return of the ex. what should i do? help!!!!?

Question

we dated for 2 yrs in the past but broke up because we argued too much. and his parents raised him like a king so he's... a tad bit spoiled. ANYWAY he dated this new girl afterwards for about a month, but when he got in a fight with her, he lied to me by telling me he was going to dump her, and used me to cheat on her (the next day he changed his mind about dumping her). this is the big reason why i'm posting this question. after she dumped him (bc they also argued) he started dating someone new. then she ended up going for her ex. after a couple weeks, he wants me back. he says he's going to change... but i don't know what to think. we got back together... but there was a time when he was already moving on without me. i wanted to be friends with benefits, but he started putting my pictures on his dorm wall and being really nice like he was when we used to be serious. and now he says that he won't have sex with me unless we have a relationship. i love him but i'm confused as he**.

we dated for 2 yrs but argued a lot.he mentioned marriage.i dumped him out of nowhere.5 months later,we tried to make it work again but break up.i force myself to see other guys,but can't stop thinking of my x.he moves on and starts a new relationship.after a month,he gets in a huge fight with her/tells me he's going to dump her/uses me for sex/next day changes his mind.this shook me bc he's not the type to cheat.she dumps him for other reasons.i later find out from the girl that they never had sex.during this,i meet a guy that's ok,but still not as great as my x.my x sees a new girl but spends way more time with me than her.she ended up going for her x anyway.2 weeks later,my x puts my pics on his dorm wall/wants to hold hands.we makeout.i still love him but am afraid.i tell him i only want friendship.he is hurt/ignores me.i agree to give him another chance bc we're best friends but the only thing in the way is our love that never goes away.so i think it's worth another try.
ADVICE?

Answer 1

Demand proof by introducing you to his parents and yours. And spoiling you with gifts (diamond jewelry) before you will continue having anything other than a platonic relationship with him. If he is serious and really loves you then he will do these things for you. If he protests, then he just wants convenient sex. You must then hold him on a tight leash until he has proven himself completely.

Answer 2

the guy is going nuts.
if you really 'love' him then give space and time.
TONS OF SPACE AND TIME.
just think about that for a second.
no time limits.
no pressure.
just until its really ready and settled...if ever.
do you have that patience?
is that something you are willing to face?
is he your friend even? or is boyfriend a technical term for someone's head you mess with while they are doing the same to you. You should consider these things and take time to talk about it and really understand exactly where you are with one another.
focus on getting through school and love your studies.
dont sell yourself short and dont set yourself up for failure by continuing with someone that is also unsure.
he already proclaimed this to you.
now protocol of respect calls for a massive cooling off period.
even before you consider moving on to meet other people do this for yourself.
friends with benefits is not going to be possible with this guy. you know it already. go be a slut with someone else if that is a priority and cool your head.
