Batty:
First all, I just want to say that I admire you for being the only woman working with a bunch of man, that made you stand out from the crowd right away, not to mention that you kept up for all these years. Everyone is insecure, and men aren't exceptions, they'd like to think that women obey them but the truth is, it's the vice versa that really holds true. In this modern world and most cases, woman is the feline, and man is the mouse. Men just like to think that they are in control. When you listen to their conversations, sit back and enjoy the live comedy, because you know better than to let them weaken your thoughts. About your love life, look, you've still got the whole life ahead of you, and I'm guessing you are probably in your mid 30's. The probabilities are that you are going to find someone sometime in your life, I know it sounds cliche but you shouldn't give up like this. I think that being scammed did a lot of damage to you, but you know what? Screw that bastard, I'm guessing that he doesn't have a good job and he won't keep on laughing for long, plus, the guilt will hit him hard. I think I know how you feel, you want a break but you have to keep working to earn money. You can use your weekends and truly enjoy your 48 hours of free time. Little is better than none. Listen to me, you've got a LOT to give, just by looking at your posts, you help everyone and you will be compensated for all your kindness. Don't even say that you are not worthy of love, everyone in this world has someone who loves him/her. About romance, the time will come and it's too early for you to give up. Don't fight your tears, let them out, go home early on Friday, watch a good movie and cry for all you want.
I wish you well.
