<human>: I'm in absolute love with him. He does the whole come here, come here, go away, come here scenario. For weeks he will be out of my life then he will come back randomly and we talk for hours. 

The thing is we have been apart for over 2 years now. And he has a girlfriend and lives with her. But you can tell from what he says and how he tries to contact me he is trying to talk to me in secret from her. It's a very odd situation. But I need advice, if he clearly wants to still talk to me and does so in secret what exactly are his motives? What do I do?

Can you succinctly summarize the text in 1-3 sentences?
<bot>: I'm still in love with my ex who comes in and out of my life still and yet he has a girlfriend and lives with her. Advice?
