Can guys in college please answer this? Please :/ what went wrong? He is 25, I am 21. Would really appreciate it!!?

Met this guy about a month ago, he seemed really nice, polite, and genuinely interested in me. On a night out, he met my sisters and talked to them and and my brother in law all night. Later that night he said he liked me so he wanted to get to know the rest of my family.

We texted all day everyday for almost a month, but when we saw each other more, the texting got slower and less consistent. He kissed me about twice and then invited me to an event from his work. I didn't know anyone there so I was quiet at times. I invited him over to eat that night for the next day and he gave me a lame excuse for the 3rd time so that kinda threw me off and the ride home was awkward.

He asked me what I was doing the next day since he was gonna be on this side of town too. Didnt kiss him or anything and he semi-walked me to the door. I texted him that night if he got home ok and he said "I did! thanks!" I replied Ok good! and the next day i texted "goodmorning" since he always texted me first..I told him i was sorry about being quiet in the car but that it had nothing to do with him.

He completely ignored that and talked about something else, only to ignore my text from then on while he was active on social media. Haven't talked since that day and that was 2 days ago. Then he liked one of my pictures on fb which was weird...

Did i do something wrong? I never pressured him into a relationship or even talked about the future.
