How can I get out of this rut?

One of my 'online friends' went through something VERY similar to you....almost to the 't'....the guy she 'fell for' was online as well and she was at the point of throwing away her current relationship for this guy who made her 'feel'....sometimes she felt happy and others she felt sad, but the 'feelings' were very strong.....I asked her if she felt 'happy and secure' more than 'sad and unsure' and she said no...so i told her to ignore him and 'delete' him and see if she was better in 2 weeks....it was truly difficult for her, but in the end, she stuck to it and after two weeks, she started slowly realizing that she was worth 'feeling happy' more than sad, so id suggest if you are feeling unhappy/sad more than half the time, 'forget' this guy alltogether. i do realize that is easier said than done...but if its meant to work out, it will....you should succeed esp. since you say you have lots of friends....good luck
