Outcome-based Relationship

When Mr Ex and I first dated, we were studying in our first year of university. Love blossomed late because I was still under strict 'no romance during studies' instructions by Umi. Anyway I flew off to UK and he had to repeat some papers and joined me a year later. So for one year we had a long-distance relationship. He rejoined me during my final year of university & we married the instant I graduated.

All in all we knew each other for 3 years before we tied the knot. We wanted to marry earlier but since we were not working yet, we had waited for security i.e. a paper qualification that'll help us for the future.

That's more or less my story with Mr Ex.

With S, he had been single for all his life. He was engaged once but they didn't make it to the altar. To this day he's probably still hung up on her, I don't know.. but with me he has not mentioned marriage or anything close to it. We have known each other since July last year because we worked on a few alumni activities, but started dating sometime in December 2015. I started prompting about marriage when we started getting close.. and no matter how persuasive I was (or how threatening), he just won't mention the word.

So, to cut the story short, because it is getting late.. I have taken the liberty to make my own conclusion about me & S:
Possibility 1: he never wants to get married, ever
Possibility 2: he wants to get married, but not to me

Anyway I have noticed that the profile of girls he dated are the sweet petite compliant damsel in distress types. Oh so help me! Wake up & smell the roses. I do not fit into the profile, he has never mentioned marriage and he only thinks of me after all his friends & acquaintance & family members have been entertained. Yet I'm still hanging around why???
