Help a girl out

I've been in this situationship for (a year in june) and we used to meet one a month irl and just flirt online once in a while and small talk online (our relationship is more real life based)

i met him when i interned at their company and we've had chemistry and tension ever since and we're both law graduates so i used to go to him for some advice (as an excuse) we're in a tension filled friendship?

Anyways he went out of the country to get his masters and we haven't seen each other in 4 months now and he rarely talks

I mainly start the conversation and he just replies every single time and i see him adding girls and liking their pictures

I want to know what am i supposed to do and he just posted a instagram story and i was wondering if i should like the story or just ignore him until he comes back

And I'm a little worried that maybe if i ignore he's going to fully stop coming back to me and i really like him
