[Grammar] How to use "stay in touch" in this context (birthday wish)...

[Anti_virus_abdo]

Happy birthday to one of the very few school friends i still get in touch with / i still in touch with / still happen to stay in touch with / we still in touch

Which one is correct? Also, is the first part grammatical?

thanks a lot in advance.

Most natural are "I am still in touch with" and "I still keep in touch with".

Your third "still happen to" is natural but creates an unnecessary note of doubt and confusion about sincerity.

Your fourth (possibly added later) "we still in touch" is incorrect. "Keep" seems to have disappeared from #2. It is no longer correct.

Thanks a lot guys. I really appreciate your time.

Your fourth (possibly added later) "we still in touch" is incorrect.

We're still in touch would work for me, however, but not in this context.
