There are two verbs: möter vs träffar
and möts vs träffas.
The forms ending in s are deponent forms with a reciprocal meaning, read more about that kind of verb in this post: https://www.duolingo.com/comment/6094592

There is also a slight difference in meaning, so that träffa (and träffas) can refer to a chance or planned meeting, but möta (and mötas) is usually a planned meeting.

"all the time" would be hela tiden. There's a small difference between that and "always".
