To know whether a boy or gal love each other, u need to hv the
feeling of "missing". If i really love a boy, i will miss him
tremedously and alway think of wanted to be with him, want to know
where he is, what he is doing, but not in a way of entering his
life and bothering him, just a goodwill that he is ok and
alright.
The moment my bf go off after sending me home at nite, i missed him
in just a few minutes, if that is not love, i do not what is should
be.
In TS case, he got no feeling nor missing factor to support his
love for this gal, suggest that u spell it out to the gal, she may
get furious or awkward, but gradually realise that it better to
speak out now then regret later. Just be frens, give each other
more rooms n chances for other romances.
