There are a lot of guys who would forgive the fact that a girl is socially awkward as long as they are physically attracted to her and they don’t feel as though she is out of their league.
Hence, if you don’t give off the vibe that you just don’t want to be bothered, there is a good chance that you will not have any trouble with guys wanting to date you.
His feelings may have changed since the date because he has now had time to reflect on the date.
You may have felt like he liked you during the date because he made out that he was really into you, but it doesn’t mean that he maintained that feeling after the date.
Sometimes a guy will reflect on a date after the fact.
