There may be a few reasons why he isn't contacting you but once every few days. Could be that hes finding it hard to find time to escape from his SO so he can write you. My AP and I only contact eachother when he's at work during the week. The weekends when him and his wife are both off we don't talk at all. Men, as I've come to realize, are not that great at communicating like women. We tend to overcommunicate where we say too much, but men usually aim for getting their point across short and brief. Now don't get me wrong, some guys are great talkers/texters where you hear from them all the time. Others its like once in a blue moon (usually because they are horny). Anyways this guy could be the latter of the 2. You'll only hear from him when he's horny and usually if that's the case they'll say pretty much anything to keep you hanging on a string wanting them (I miss you, no regrets, its not just sex with you, I like doing other stuff with you besides sex). You have to remember, he has a spouse that he does those other things with, so he may very well just want sex(whether it be phone, cyber, or in person) with you on occasion. Honestly I would lay back some and let him come to you. And if he doesn't, then its not meant to be.

I had one AP who before we first met up, he talked to me all the time up until our first night together. Hes said/done things that just melted my heart and made me go crazy over him. And this was all recent too. He's the reason I made this account actually. And after that first night together our messages grew longer and longer apart til one day he said he had to tell me something he's been needing to tell me for awhile. And that was he started getting serious with this other girl and he doesn't want to mess it up. So i laid back and wished him luck and that the girl was lucky to have him. Few weeks go by with barely any talking and I sent him a snapchat just giving a friendly hello and we start talking again. I make a flirty comment and he flirted back and I ask how are things with his new gf and he mentions they aren't together any more. That she didn't support his plans for the future so he ended it. Queue me to make my move to meet up again. We ended up meeting up a couple times and then when I tried setting up a movie date and v day date at my house with him, he cancelled both times. So after him not saying much on v day weekend, i finally wrote him the day after and told him if he wants to see me, then its up to him that I give up on trying to see him. I didn't talk to him for a few days, but i messaged him a hello one day and he wrote me back an hour or so later and we talked for a little. Haven't heard from him since. But he looks at my snapchat story every day late at night. So idk. Im just letting him be and seeing if he'll come to me. In the mean time I'm not cutting any prospects off my list for him because even though I really like him and could've seen a future with him, I'm pretty sure his feeling isn't mutual and everything he has said to me when we were together in person were just to keep me hanging on a string for him. So yea, not exactly same situation as yours, but just similar feelings ive had for him, and him pulling away like yours did.
