As hard as it may to admit - it seems as though he found you worthy of dating / having as a gf - but he was not in love with you enough to want to marry you..... and this too is OK as many people date, live together and become lovers with out ever getting married.

I personally would advice you to move on and forget about him...... and if you have not yet gotten the kids bike back from him it might just be time to call the police so you can safely retrieve the bikes.
