Social media and ex T

I have recently joined twitter (mostly to promote my online poetry and keep up with writers news). I know that T1 is on twitter and he uses it infrequently (has done about 30 tweets in 3 years). His tweets are only open to confirmed followers.
I'm currently debating whether I should follow him. I am trying to analyse what I want from it, and what it means for me. I feel fairly sure he would confirm me, because while I was still seeing him he sent me an invitation to join his google circles (but I don't use google circles so I never responded)
I do want to retain a glimmer of contact with him and that is the primary motivation. In our termination session he said he would continue to read my online poetry, so I think it makes sense to be in communication with him that way. But the questions keep coming back to me: Will this make grieving for him harder? Am I ultimately looking for something unattainable? Are there other underlying motives? Would it be a devastating rejection if he didn't confirm me or follow me?
I'm not sure whether I'm overanalysing this or whether these are genuine problems that I could face.
Does anyone have experience staying in touch with an ex T? Has anybody used social media? How did it work for you?
Any thoughts or experiences would be really useful for me. Thanks
