WIBTA if I start getting feelings for someone else while in a relationship
So me (18M) and my gf (18F) have been dating for a moth or so and I love her so much but I have noticed she is acting a bit dry, so let me catch you up real quick she added me into a Group chat with two other people let’s call them Alex (19M) and sara (18F) so we talk awhile and now I’m getting closer to them by the day. So flashback to yesterday I saw scrolling on TT when Alex sends me a dm it says " a little birdie told me that someone is not texting their girlfriend" so I panic saying "wdym?" Alex says " you haven’t been texting your girlfriend a lot care to explain" so I explain I am packing for a family trip and haven’t had time to be on my phone. And then Alex says it’s fine just remember to text her, I respond with okay. Now we are at today it’s 13:40 on Sunday June 7 when I get a text when I wake up from my girlfriend saying " can we unmatch cause Sara is not feeling well" me thinking that was wierd cause she was fine yesterday but whatever I reply with " oh ok yeah I don’t mind what ever keeps Sara happy" that’s when she starts ghosting me I tell Alex about this he understands me. I get another text from my girlfriend saying " you can match with Alex instead" I reply with ok so me and Alex are thinking on what to match with our pfps and we decided on two anime characters from the summer Hikaru died. That’s when it hit me, do I have feelings for Alex. I think in my head no no way I love my girlfriend. My mind goes blank and all I hear is getting messages from Alex. So help me Reddit should I stop thinking about Liking Alex and focus on my girlfriend or should I confess to Alex sometime in the future that I like him and break up with my girlfriend.
