First Blob

So for my first blog I thought I would talk about relationships as it has been on my mind as of late. I have been in several relationships and they were fine but what I want to talk about is users. Specifically girl users. Somebody I know, let's call him F, has started going out with someone this week and it seemed normal, despite the fact they'd only known each other for a week. Now at first he said he wouldn't leave his mates for her and he has already done this before with another girl. But this is easily put aside. The second thing to annoy people is after one day he told people he loved her which seems desperately needy. And today I learnt that he has been buying her things that she asked for without a care and she has been giving F anything back which leads to us all thinking he is being used. Now I'm friends with the girl and I didn't think she did this sort of thing but she does. He has suddenly turned back into a dog and she is a supposed user, a bad combination, am I right? So what I'd love to know is why do people go out with people they don't know and don't suit? Hopefully F sees the light before he alienates himself from all his friends, again.
