i have ex boyfriend troubles.. anyone shine some light!?

[Shannon]

Okay, so this is probably going to sound really lame, but its confusing and constantly on my mind at the moment and its making me act weird with my current boyfriend who i've been with for a year and a half.

So a week ago I fount out that my ex, had started following me on instagram, now this is very strange considering 4 years ago(when it ended) he wanted nothing to do with me and wiped me from his life.. he then got a girlfriend who my friends told me he was with for about a year and they recently broke up . SO now he's following me on instagram (this is like facebook, but you post pictures instead of status' its a mobile phone app for anyone who doesn't know) and occasionally either once a day or once every two days he will like one of my pictures.. is he doing this because he likes my picture or does he want me to talk to him? I wouldn't know what to say or what but its really confusing. Me and my ex were childhood sweethearts. we broke up when i was 16 and i'm now 19. my ex didn't date anyone for a year after we broke up nor did i.
I just need a little light shining, am i thinking too much into it or what? if i was to talk to him what would i say?

Say 'grow up.'

Do u want to be with him again. If not. Ignore him and block him.

Life's too short to play games

He's messing with your head. Dude, don't think much of it and actually you shouldn't even be thinking about it at all if you're with a new guy you're in love with. Let him do whatever he wants, don't even care. Don't say anything that would be messed up to your current boyfriend.

all depends on you,if you want go back again and start your ending story,or if not just ignore him,block him i think this is perfect for you.
just think alone and take a best decision.

He is obviously showing interest in you. Its up to you now to take the action. If you still have some feelings for him then talk to him. If you just want to be friends with him, then be comfortable with all the photo LIKES you get from him. If you don't like being stalked by your ex - block him and send him a message politely that it is bothering you.

Good Luck
