What's up with you?

I don't understand you lately..
You're different from the way you were last week..
You started texting me again..
You started texting me good morning this morning...
You called me again this morning...

Just about time when I'm training myself to let you go..

I don't get that excitement anymore when you called me..
Instead of happiness I feel sadness..
I guess I'm a little numb...

I tried to laugh and be cheerful as usual..but I couldn't..
If you ask me whether I like you as much as last week? No I don't...
I'm trying to let you go
I've been building up walls to cover myself..but now you're back to the way you were 2 weeks ago..

What's up with you?
