So, I (M24) recently went on a date with this girl. We were chatting for some time before, I really like her personality and i knew she was a lil chubby. We decided to go on a date and when i was halfway to the place we agreed to meet in she sent me a message, where she said that photos on her profile are a little old and that rn she might be a lil bigger due to health issues, and that she's doing everything she can to fix that. I answered that it's not a problem, mainly because, again, i was already halfway to the place, but also because i thought it might not be as bad. Well... She was... Significantly bigger irl... Anyway, we walked through some places, had a dinner and I genuinely like her personality, but she doesn't attract me physically. I didn't make any risky moves, we mostly just chatted. Now, what i really feel like an asshole for, is that right after a date we sent each other some messages, and I said that everything was great and that she's cute(because i do that all the time after dates), for which I feel kinda guilty since I feel like i might've given her some false hope. What should i do now? Should i try and hope in her words that she's gonna fix it? Should i reject her? If so, how do i do it more gently?
