I SO LOVE MY BOYFRIEND BUT HE WON'T COMMIT TO MARRYING ME

Hi RTers, my name is Bisi (not real name), i am a banker and considerably doing well. Right from my younger years, i have always wanted to get married early, but at age 27, life hasn't worked out for me as planned Maritally. As i write this letter i don't even know if I'm in a relationship or not. I ought to be in a relationship with Dave (not real name), but he has repeatedly told me that he isn't committed. I met Dave 2 years then i was a Virgin, we dated for 6 months before he broke up with me, reason being that i wasn't ready for a sexual relationship. I like and loved him alot, he was the kind of man i wanted in my life, but sex before marriage was a big NO for me, however to be honest, the day he broke up with me was the day i had made up my mind to let him have me. Well it wasnt to be and i moved on and met another guy who this time i allowed to dis-flower me hoping that would keep him by my side till marriage, but as i had always known about men (most of them just want you for s3x and move on) and he was not different. It was shortly after that episode Dave came back into my life. He apologised for leaving me back then, told me so many stories of how he missed me and so on. initially i wasnt going to have him back but after he spoilt me silly, i again reconsidered him. I told him i was no longer a virgin and he was kinda disappointed but didn't make a fuss about it, he just wanted me back, so i took him back. Truth is that i don't think i ever stopped loving him so it was an easy decision. We started having s3x of course and he was kinda almost insatiable, but i didn't complain. Lest i forget, he is one of the top managers in a corporate big company in lagos, he is 35 years old and has his own house in Lekki and doing very well financially. After a few months of frolicking together, i gently popped the issue of marriage, and to my surprise he said that it was not in his agenda anytime soon; that he has so much more to achieve before marriage. It really sank my heart because i thought that was where we were heading. I then boldly asked him what his plans are towards me, and he said we should just enjoy ourselves for the now without thinking of marriage, that it complicated things but if however i am not satisfied with the arrangement, im free to do what i like. Since then he has been very cold towards me; always choosing to hang out with his friends than me, rarely calls except when he wants s3x, read my chats without reply for hours, doesn't give me a dime (not that i care about that before), he has just been very distant  despite my efforts to be closer to him; like he's pushing me away. Whenever i ask him if anything is wrong, he says nothing. Occasionally he becomes loving but most of the time i am just alone and empty. I know i should perhaps leave him, but i love him so much and there isn't any 'Toaster' around that compares to the him in the qualities i seek for.

Dear RTers, just want should i do?  I really so sad.
