girl paid for date and guy lied about living alone(lives with ex) plz help

i was following this guy on instagram M(20) and me F(18) for awhile and i always thought he was super cool and cute. he posted bmx videos and it really impressed me. then later on we matched on tinder and we started talking occasionally. and then he called me pretty and i called him cute!! then we started talking everyday. around the time we started talking a lot he had a trip planned to go to california to see his dad. he was going to be gone for two months. (didn’t have time to see him before he left) me and him still talked everyday when he was in cali. i really liked talking to him and i had a big crush on him. then when he got back he was superrr distant all of a sudden and i wasn’t sure why. after some time passed we finally got to hangout in person and go on a date. i picked this cat sanctuary place!! it’s free & cute and u can just chill and play with cats. he picked dave and busters. the cat cafe was rly fun and he was very nice. we ate first at dave and busters and i just got fries and water because i wanted to be cheep since i know he has a lot to pay for living on his own. when the bill came he asked me if i wanted to split and i said okay. then it was time for games and i just took out my wallet and paid for chips. my debit card declined three times and he kept saying it was declining. i just took money out from my savings and paid for the games. it was really fun playing with him tbh. then we ran out of chips and it was really awkward. like i didn’t wanna buy more but i didn’t wanna ask him about paying so i just asked if we should be done and go home so we did. he texted me and told me how much fun he had and that he was sad cus i seemed like i wanted to go home at the end. when that wasn’t really the case it was just an awkward situation. i honestly was super disappointed in the date. i told myself to give him another chance because he’s probably just a broke young adult. we started to plan the next time we were going to hangout. he suggested he came to my house to watch batman and go to the park but i suggested we should go to his place instead since i still live with my parents and i was nervous to bring i guy over in front of them. he actually agreed. literally two days later he sent me a picture of his food on his table and i saw a phone in the picture. the phone case was colorful and it said “self love” on it. so i asked him where he was and he said he was at home. and i was like “i see.” and he said “what” and i said “oh nothing i just thought you had a girl at your house” which he replied “why would you think that 😂” and later deleted the message and then sent me a paragraph that he lived with his ex girlfriend and that he’s sorry for lying about being on his own.” i felt so betrayed. i honestly don’t know why i jumped the gun and said that to him but something just seemed off. he only facetimed me when he was outside on a walk and i noticed that there were crystals in his apartment and his ex liked them. but i’m stupid and thought she helped him decorate or were a gift. like i truly believed he lived alone. i really believed him. i’m just hurt and we are taking a break from talking for awhile. i stopped talking to him for days and then he texted me saying that he’s going to text me later when he’s felt like he’s changed. i really liked him. i think it’s because i never really had a guy ever treat me well before and i thought too highly of him before getting to know hi
