Is It Bad?

He left me, I was okay with it at first.
We stopped talking, I pretended like I didn’t care.
He has no idea how much he hurt me.
Three weeks ago he text me, we hadn’t talked in about a month, said I miss you, I fell for it.
He talked to me one day, then was gone again.
And then texts me a week after my car accident and says 'I’m sorry my phone wasn’t working', fell for it again.
Then we didn’t talk for a week. On one of my accounts, 3 days ago, he comments on a picture
'Your so beautiful.
Ps. I miss you'
We talked all day that day, I missed him.
I text him the next day, no reply
Did the same the next day, still no reply.
Today I found out he has a girlfriend.
I’m crushed.
I’m hurt.
I’m sad.
I don’t know what to think.
I keep falling for his bullshit.
I looked the girl up, she’s pretty.
But I hate her.
I don’t want them to be happy.
Is it bad that I feel this way?
