You can be very outgoing and jovial but if you don’t make eye contact with guys and smile, many won’t approach you.
Most guys overthink.
They worry about rejection immensely.
As a result, most of them require strong signs of interest in order for them to even think of taking a chance on approaching a girl.
Something else you could do is look to your girlfriends.
If you have girlfriends that tend to get approached by guys, it may be to your benefit to ask them about what they do or even emulate some of their body language, if it fits your personality.
There may be something that is missing in how these guys read your body language that they need in order to approach you.
Your mutual friend may have indeed put him on the spot when she asked him if he wanted a relationship with you.
Instead of giving him a pep talk, she may have actually dissuaded him from making any moves on you.
That being said, she could have been an opportunity for him to connect with you as the middle person and he didn’t take advantage of that.
Thereby, in that instance, it may have been a combination of being put on the spot as well as not having a strong enough desire to take advantage of the fact that your mutual friend could have been used as a way to connect with you.
Your college closing due to the coronavirus scare was bound to happen.
Perhaps this time away will help him get more clear on his emotions and enable him to develop a plan of action to approach you when college reopens.
One can only hope.
