I'm not trying to burst your bubble here OP, but for goodness sake, why are you on a dating website?! Those sites are horrible for women. Women usually join dating sites in the hope of finding a loving partner, men do it to find a quick, no strings attached shag. I am very suspicious of men who join dating sites. I mean, what is wrong with them? Can't they find a lovely girl anywhere else? There are thousands of fantastic women to choose from in their every day walk of life, but no, they join a date site. You have to wonder why (I would). Date sites are wonderful places for these men. It is a bottomless pit filled with eager women, waiting for them, hoping for them, pining for them, swooning over them. Sorry, but no self respecting, dignified woman will lower her standards by allowing herself to be exploited like that. Yes, there are some success stories, I know, but they are very few and far between. Your chances of finding your life partner on one of these sites, are about as much as your chances of winning the lotto.
Why don't you get out into the real world? Join a book club, do volunteer work, join a hiking group, go to church (if you are so inclined). The possibilities are endless. Here you will meet real people, with real lives. You will make new friends, friends who have brothers, cousins etc. Do your shopping at the same shop every day (week), smile at the cute guy who has things like ready-made meals and quick soup in his trolley, strike up a conversation. Browse in bookshops (you'll be surprised how many cute guys hang out there), also you'll know that he'll have a brain. Don't belittle yourself by just becoming another number or photo (one of millions) on a dating website. You are worth more than that. I agree with others, you sound absolutely lovely - I know a couple of men who would love to meet someone like you. Don't degrade yourself by becoming some one's 2nd, 3rd, 4th, 20th choice/option.
As for this twat that you dated the other day. If he really liked you, he would have contacted you before you even got home from your date. If he really liked you and saw you as a 'keeper', he would have been petrified that some other bloke was going to get to you, while he was away on his 3 week business assignment. He would have CALLED you everyday (not send an effen text - which he didn't do in any case) to hear what you were up to. He would have had flowers delivered to your door. But did he? No. I'll tell you why. He thought you were nice and all that, but he is keeping his options open. He probably has a herd of willing females on his email list and he is keeping them all dangling until Miss-Perfect-blows-his-pants-off comes along and I bet you he will phone her every day and have flowers delivered to her door. He will make sure that his next work assignment is near where she lives. He will drive right through the night, in a car he borrowed from a friend, just to pop in in say hello to her. He won't care that he will be knackered the next day, because she will be worth it. YOU deserve to be that woman. Sorry.
