I have dated clingy girls and also simply huggy girls. Both can be interpted wrong depending on my mood / experience at the time. So ask yourself if you are actually too intense or if you are looking for someone that is ok curling up a lot etc.
Say sorry and ask what might be classed as too clingy for him then think if that what you class as too clingy. As without more information it's equally possible he freaked out over nothing.
There is nothing you can do to fix the situation unfortunately!!! I have dumped exGFs for very similar reasons!!! Being too clingy and needy is a form of insecurity that only you can change otherwise the same thing will continue to happen in your future relationships to come.
Don't. I appreciate girls who are clingy. Those are hard to find lol. So yeah if you lost him then he wasn't the one. And you going after him will seem even more clingy. So go find a guy who'll appreciate a clingy girl. I'm sure there are many guys who do :)
Go after a guy that will enjoy your clingyness. You deserve to accepted as you are and shouldn't have to prove anything or worry about being anything but your authentic self. Anything else is just a waste of time
You do realize by trying to contact him you're being clingy right? You need to forget about him and start with a new guy who doesn't know you as a clingy person. There's pleanty of places you can go if you don't know what that looks like
