Dear Questioner
I dare say it’s not necessarily a bad thing that you still trust in people. Trust is never quite a bad thing to have (for the most part). However, perhaps it’s who you put that trust into that you need to change. I get that your probably putting what hopes you can into meeting the right guy, so when the chance comes along you go all out and hope for the best. Only to be let down in the end. In saying that, maybe it’s an innocent coincidence that they have to cancel. However, that could be a bit bogus. Ultimately, maybe just be a bit more weary as to whom you place that trust in or even try to hold back just that little bit so you’re not crushed if things go badly but you can still be really happy if they turn out ok.
