TIFU by accidentally convincing a great girl that I was talking to other girls and lying to her about it

Not really sure why I’m posting this. Maybe just to vent or as a cautionary tale. I (31M) dated this girl (28F) for 6 weeks. It was really great. I’m generally very awkward and don’t have hardly any relationship experience, but everything was so easy with her. She was really fun, sweet, caring, beautiful, funny, and overall a joy to be around. There was a language barrier (she only spoke Spanish and I spoke very little Spanish), but we had a lot of fun together and were still able to get to know each other and bond well despite it. She just ended things though because I committed a series of incredibly stupid fuckups in quick succession and obliterated her trust.

Fuckup 1: while hanging out this weekend, she saw that bumble was still on my phone. We hadn’t had a conversation yet about exclusivity, but were acting more and more like a couple (hoodie stealing, hand holding, frequent dates, lots of other little things). I was thinking heavily about making it official in the next few weeks and intended to delete dating apps before I did. I had not had any interest in talking to any other girls since our first date, so I was not using the dating apps at all anyway.

Fuckup 2: Upon seeing that she was upset about seeing the app on my phone, I froze a bit and in my broken Spanish I accidentally told her that “I don’t use it much” instead of that “I don’t use it at all anymore”. So she obviously heard “I still use it a little”, and I didn’t realize until later. I could have eased her mind by just tapping the message tab to show her there were no active matches or conversations, as there genuinely weren’t. But for whatever reason, my dumbass brain did not consider that as an option until it was too late. Also, instead of reassuring her, I just asked her if she used bumble (???), to which she obviously said “no”.

Fuckup 3: Later in the evening when we were at dinner, it was obvious that she was still really upset, so I asked her about it. She mentioned that in her last relationship, her ex was talking to other girls on bumble while they were together so that was a big deal to her. I tried to reassure her I wasn’t talking to anyone else, but again, for GOD KNOWS what reason, it still did not cross my mind to show her that there were no messages, or to just delete the app in front of her.

Fuckup 4: That night, after I take her home, I delete the app. I don’t think to delete my account until after I’ve already deleted the app. I think to myself “it’s not that big of a deal, probably not worth downloading the app again just to delete the account”. Wrong! The next day she downloads bumble to see if I’m still on there and lo and behold, my account pops up. She asks me the following day if I’d deleted the app. I respond that I had deleted it 2 days prior (I had!) She says “that’s weird, why did I just see your profile on there yesterday?” Oops! Not a good look! I try to explain that I forgot to delete the account, but that the app isn’t on my phone anymore. She understandably isn’t believing it. She essentially tells me she can’t trust me anymore and that it’s over.

So now, after all that, and truly not using dating apps while we were together, my relationship with this beautiful, fun, amazing girl is over because I can’t communicate or not be a dumbass. Maybe it’s better I don’t breed! Don’t be like me, I guess!

TL;DR - I accidentally did everything possible to convince a great girl that I was a lying scumbag who was talking to other girls behind her back, resulting in the end of our relationship, despite not talking to a single other girl during our time together.
