Too long to detail… but like why do people lie for dates?

I’m a lil but hurt because I was kinda catfished but like I wasn’t… I went on a date, (well 2 today) one with a guy who was fine as hell but lied about his height and I think he lives with his girlfriend… tf? The other was with a woman and idk if she’s my type… hella sexually aggressive… like HELLA. Like I’m with the shits but I just met you sis, give it a few more dates, jeez.
