Oh HAHAHAHAHAHA!!
I didn't think there could be two Arce's but here we are. 
Considering the stigma you have for unmarried people, and as the clock keeps ticking faster and faster; and opportunities diminish exponentially, and the time comes to "settle" with a stoic resignation, suddenly decent men with "gentle hearts" who isn't so quick to betray the "sanctity of sacred text" won't look so naive, gullible and even weak.
A man in his fifties in reasonable good shape and decent income still has a pool of women 25 years old and up available. A women in her forties. Not so much. Especially a "plain Jane."
I suggest that you be a little bit more appreciative of gentle hearts and one not so quick to betray the sanctity of unspoken agreements or even formal vows.
