Me [36 M] with my gf [40 F] of five months, has been checking on me through the app we met on and accused me of cheating

I got out of an abusive marriage about a year ago, and started dating someone I met on a dating app about five months ago. Everything seemed to be going really well, and she was understanding about certain parts of my life, i.e. when I had my kids I wouldn't be seeing her.
She sent me a text the other day asking if we could talk about some concerns she had. We spoke and the run down was that she had been checking on me through that app we met on and thought I was still using it to meet other women because my profile was still there. She also said that the location it kept showing was concerning to her. I had deleted the app from my phone maybe after a week of us meeting, really hadn't thought of it from then on. I felt pretty violated that she was doing this. She thought I was repeatedly going to a city I haven't even been to in months.
I explained to her that I had deleted the app and that I hadn't thought to actually delete the profile. It seems pretty hypocritical that she is was getting upset about this, when she has not told me she never deleted her profile, or the app from her phone. It even came out that she still has multiple dating apps on her phone with open profiles.
In our conversations that we have had since, she has said a couple other things that really bothered me about my ex controlling my life and the quality of my friends.
Am I out of my mind for thinking this is a pretty significant line to cross? My gut feeling is that I should end the relationship over this.
tl;dr The girl I've been dating has been checking up on me through the dating app we met on, and accused me of cheating
