Never trust guys from dating app even if they say unrealistic things to trust them !!!

Not into casual but something genuine ( wrong place to expect such things) . So i was talking to a guy and after that i deleted dating app n all and was consistent with him. Gradually we become close to each other started spending time. One fine day eventually he started having less conversation or no convo at all i asked him ki what happened he was like i m not doing well in life work and stuffs. But after a week my frnd saw him in dating app and showed it to me ( i was surprised ) that he recently made the profile n i right swiped it from my friends profile and “ hurray” they matched! I took a ss and send it to him and with grace he said “this is not me “ may be old one ( but with recent picture) lied enough. This guy told me that i m into long term this that i like ur vibe n shits. I feel this was one my stupid decision to trust guys frm dating app.
