Marriage Proposals

How does one handle three marriage proposals in a day.

Accept the first.
It wasnt for me. It was for the lovely young woman who lives in my house. The boy's family came to see the family of the girl's, brought a ring and left it for the girl and her family to consider. Its just a formality. The fact that they were welcomed for the visit was already a tacit acceptance.

Reject the second with no concern of his feelings.
Is there any other way when he is married, with a mixed-bag of children at that? Out of love for his two children, I have maintained a friendly relationship. However, when he keeps making his intention known to all and sundry including his family, his children, my family and my friends (asking them to plead on his behalf), I have no option but to avoid him as much as possible. Where is his brain? Well, his children say that its in his knee-caps, so I guess I'm gonna have to smash his knees to knock some sense into him.

Reject the third delicately.
There is love. There is affection. There is hurt too. A year ago I told him, its now or never. We continued to keep in touch, meeting every couple of months. Some 3~4 months ago, I repeated that call when my heart somewhat softened. Still, nothing happened. So I made other commitments taking into account a life without him. I took up a new job which will last me up to 3 years. I met new people. I started new and rewarding relationships. In a space of a mere 3 months, too many things have changed such that to build a life with him is no longer important. Worse, it no longer feels right. How do I tell this man whom I have loved for many years, without hurting him? No sense in keeping this hanging over us. When he made the proposal late that evening, I told him as it is. He didnt believe me. Two weeks on, he is still in denial. Its as if he hadnt heard me. Next step: Quit him cold turkey.
