I have had 2 major crushes on 2 girls from work in the past 18 months

I am a guy in my 30's who has never had a girl friend and who has very poor self esteem, I am over weight and don't go out much. In the past 18 months I have had 2 major crushes on 2 girls from work, I got over the first one when she starting going out with someone but that was torture to go through and then this other girl came along who I'm not over yet, who is still single and who has started to ignore me on face book.With both girls we used to text/ fb message every day and I started to get attached, I don't think the first girl was ever that interested in me from a relationship context but I definitely think I had a shot with the second girl as she was very easy to flirt with and we even went out for food and drinks but I fcuked it up because I was too needy and didn't act fast enough, I don't know what I'm looking for here, I just need somewhere to vent. The first girl and I are definitely just friends now, we still work together and we text each other the odd time but I have no feelings for her anymore. The second girl has since left and if I fb message or text her she ignores it now. I am considering defriending her from fb but I'm worried it may come off as childish but in another way a clean break could be good and not to see timeline updates from her page anymore may also help, I know myself that to feel this level of oneitis for 2 girls when I've never even had a relationship with either of them is sad needy and reeks of someone with self esteem issues

The way I see it, you're placing too much importance on a girl's friendly overtures towards you.

You need to relax, keep it friendly and casual.
You sound like a good person, who is putting a little too much pressure on yourself. Girls spot this and will back off. Try to show your fun side. Believe me, it's there, you just have to toss that needy side away.

Be fun, casual, friendly. No pressure on them or you.

Get involved in something outside work - sport, whatever you're into, just make sure it has a good blend of people. It does help.

OP, I think what you really need is to work on your own self esteem issues. It really is true that you need to have a good relationship with yourself first.

When you are content with yourself, someone who is right for you will come along. That's not to say you should stop looking for love, but I don't think you're going to find it with either of these women so you should move on.

Have you considered counselling for your self esteem?

De-friend the second girl, you're not friends so why bother keeping that link there when there's no reason to? Forget about how it might look to her, she doesn't matter anymore.
