Is he interested?

I’ve been talking to someone I met on a forum about six months ago, and we’ve been emailing back and forth on a fairly regular basis.
As a matter of fact, we’ve been exchanging photos as well (nothing sexual). A majority of the photos are selfies, or places he’s going, or things that he’s doing.
He’s aware of my former weight problem, but had mentioned that he thinks that I’m attractive(and had gone into great detail about the features he adores), along with being smart and strong – adding that I’ll have a bright future ahead with tons of suitors. He’s also mentioned that I’ve inspired him to work out as well, and keeps me updated on his progress and what he’s doing (I’ve recently gotten into body building). We haven’t exchanged numbers yet, but he had added me on Skype – we’ve messaged each other there a couple of times. He’s been nothing but encouraging, and very kind. Not to mention a playful joke or picture every once in a while (He even posed in a certain way because I said I liked it). We’ve talked about meeting in a roundabout way, but nothing is set in stone.

Would I be wrong in thinking that maybe, just maybe, this person might be slightly interested? Our am I deluding myself?
