Ex contacts me on Facebook with friend request?

My ex boyfriend whom broke up with me a year and a half ago recently sent me a fb friend request. Since our break up he would always wish me a happy birthday but I would never say anything expect a simple "thanks and how are you?" When I got the request I asked him why he re-added me when I deleted him after the break-up and that he would never answer any of the response messages I sent when he messaged me on my birthday. He was all nice to me asking how I was and saying that he wasn't ignoring me but that he might not gotten any messages since my birthday last year (which I never sent any) because of his privacy settings and that he would send me a screen shot to prove that he wasn't lying. I sent him a brief message answering him on what I've been up to like starting school and he answered back saying he was so happy I got into the program I wanted and told me what was new with him.

I was very hurt when we broke up as he was my first real boyfriend but I've dated other guys afterward so I really don't have any strong feelings for him but I feel comfortable talking to him as we were friends prior to being in a relationship. Plus the reason why we broke up was because we were both in a state of transition at that point in our lives. Should I accept the request and could him contacting and re-adding me on fb possibly mean he is becoming interested in me again or is he just trying to be civil?

We kept comunicating back and forth through fb and evenually text messaging and ended up meeting for coffee. We talked for about an hour and a half and when we were saying goodbye he mentioned getting together again and doing something together. I ended up accepting his friend request. Is this a possible sign of him being interested in me again?

After all that, we've been back together since September and everything is going strong. I found that our relationship is actually better than when we were first together. He is much more affectionate and comfortable with our relationship. Life can be crazy sometimes.
