Lately I have made quite a few new friends some of which are women. I little background with me is that i havent been in a relationship for a long time now (i'm a 28 yr old guy) and don't have many friends.
So lately i've found myself becoming increasingly jealous and paranoid that some of my female friends have or will get together with other guys some of which we are both friends of. I have this sick feeling even thinking about it.
The confusing aspect is that with me I don't want anything to happen with any of these women and just see them as friends so I wonder why I feel so jealous?
For example last week I befriended a guy and one of my initial thoughts was that what if he met a particular female friend of mine and got together, id be so jealous as he seems her type. I can't explain why I would think that though?

I think maybe I feel jealous as I don't have a relationship myself so I feel I am being left behind maybe and want what they have i.e a relationship with a woman?. But then why do I feel jealous of them in that I selfishly dont want my female friends to have male friends as I see them as some kind of threat to our friendship. I don't feel the same really with their female friends.
It it like I want them to see me as their best & closest friend and I do not want someone else to come in and take over and demote me either.
If I found them attractive and wanted something more than I understand the jealousy but I don't which is very confusing.

Thank you for reading.
