<human>: Can you give me the gist of the text in a nutshell?

As in the title I keep messing up with woman I really like by coming on way too strong. When I meet someone I really, really like it just seems to completely consume me, I can't think about or enjoy anything else and just want to be with them or talking to them all the time and as a result I come on way too strong and scare them off.

I met a girl about 7 weeks ago and we both liked each other but she had just come out of a bad, long term relationship and wanted some time on her own. I tried to be patient and give her time to get over it and we've still been seeing each other and chatting the last few weeks but I just can't control my feelings and have completely messed up any chance of a relationship up by being too forward. Now she "just wants to be friends" but said that if I "had taken things slower it would be completely different".

It's so frustrating, I know that I'm doing it, I tell myself to back off and not contact them for a couple of days. Or that I shouldn't send this message, it's way too forward. But it's a constant struggle not to and I always end up breaking at some point and saying something stupid. I feel like a total creep/loser. 

What's more is that these feelings go as fast as they come. Now I know it's over and I've got no chance with her I'll probably be completely fine in the morning and not have any these overwhelming obsessive feelings. In fact I'm already feeling a lot less depressed and stressed right now and this happened about an hour ago.

Although I have had relationships in the past, they are fairly few and far between, last one being nearly a year ago now and it is not often that I meet someone I really like who also shows interest so maybe it's just loneliness/desperation. I don't know, but I need to learn to control it.

So does anyone else experience these kind of feelings and have any advice on controlling them?
<bot>: When I meet woman that I really like I become completely consumed and frankly obsessed by them and end up coming on too strong.
