NO ... He should NOT be messaging you everyday to make you sure.
If you are that insecure, you are nowhere near mature enough to even be in a relationship.
I like this guy and he notices me alot looks at me like all the time and even message me from time to time. But i like him wayyy alot and am a bit shy. If he likes me how will i know? Should he be messaging me everyday to make me sure?
Some people can be especially hard to read. They might like you a lot, but might also make sure you don't know. Respond positively to him just to make sure he knows you're good with him talking to you at least. If you don't want to/aren't ready to flirt back yet, time will work it out.
Ya all going thru hormonal phase and until you do something to stop that milling down. Uncertainity will persist even if you grow up.
