He's being so clingy?

in my opinion he really is an insecure guy. he can never be too secured that you love him because he's always unsure. that's why these people sometimes gets reaaaaally easily jealous over small things(for example talking to other guys). he needs constant reassurance that you love him. just tell him to relax and tell him to limit his calls and texts since you also have to do something else important. show him you've got your limit.
