<human>: Condense the text into a few key points

So we've been together since last October, so basically, a while. We used to text pretty much every day. I get that these things taper off. We started texting less, but would still both initiate hanging out. He'd seem like he wanted me, etc. 

We did go through a bit of a 'DB' situation, but in the past two months we've both really stepped our game up and have really incredible sex every time we hang out. (Not often enough in my opinion)

He's been really busy with work lately, as have I, but in the past month or so he has entirely stopped texting me. I have to initiate always. We almost never hang out anymore. We have sex once a week if I'm lucky, but often we go longer than that. I remember when waiting two weeks due to illness was unbearable!

Last week we met up after we were both done work to hang out and grab some drinks. He held my hands, kissed me in public, we went home and had three hours of incredible, mind blowing sex, and then cuddled and talked for another hour, before having sex again. Then we went to see a movie a few days later. We met up minutes before it started, and he went straight home after. The next day, we did a "double date" to see another film, and all four of us grabbed drinks after. The other couple went to fornicate afterward, and my SO decided he was going to meet up with a friend, ditching me entirely. The other couple drove me home. 

His birthday was yesterday. I texted him the night before to wish him a happy one, didn't get a response till 20 hours later with virtually nothing to it and was at no point invited out to celebrate. 

I am also super hormonal so maybe I am just being paranoid, but maybe I'm not. Is it over? Does this sound over? It's so confusing when he's so intimate with me sometimes, and then other times acts like we're not even acquaintances.
<bot>: He's hot then he's cold, he's yes then he's no.... texts me never, "ditches" me, have sex like once every 2 weeks.... should I brace for the worst???
