Search Results: does he love me, flirting

I've been with my boyfriend for over 2 years
he's never cheated on me
I've never cheated on him

But when we argue, I get really pissed off
And sometimes he does or says things that will make me doubt if he's really the guy for me
So after an argument, I would go text other guys and flirt with them
Or go on a dating app and talk to random guys
But then next day, I stopped talking to all of them
And make up with my boyfriend

Is this bad? Wrong?
I do this often
But i do truly love my boyfriend

He tells me he loves me. He gives me everything I want and treats me like a spoiled princess almost all the time. He's told me less than a week ago that he genuinely thinks I'm his forever person. He's cried his eyes out also less than a week ago because he thinks I love his brother. Even as I'm typing this, I just got home after being at his house for a week straight and he's on the phone with me for the night to help me sleep because of my anxiety. He's told me he won't flirt with other girls or do anything. He puts up with a lot from me and never dips out on me. These examples ones that have happened AFTER our second break up. He's also my first. We've broken up twice. The first time because I tried to overdose; the second because of PTSD flashbacks of abuse that I endured from the boy I dated on our first "break". He hasn't been with anyone else since we first started dating. People, mostly guys, around me are saying he's using me because we aren't together but we still have this kind of relationship where he loves and takes care of me and I honestly kind of cling to him. What do you think? Does he really care or are they right? He's not always nice to me, but mostly he is.
