Your background story (the 3 year relationship) sounds strikingly similar to mine. Like you said, 'picking up' was never something I had to do prior, but am *trying* learning how to do it now. So keep in mind I can't give mPUA or even PUA quality advice, but I can certainly give you the opinion of some one in similar shoes.

I tried to pay as much attention as I could to these “signs” and only came up with the fact that she did go out of her way a couple of time to touch me in a playful kinda way, but other than that Im at a loss. Im a little worried that things are going in the wrong direction because although joking around and stuff is good, its almost like that’s ALL we do now. So theres really no serious stuff happening, just all making fun of things/each other.
It sounds like she's definitly interested, and it would be safe to assume her touching you is a huge IOI. Making fun of each other is a great way to be C & F and can build attraction. I think everything hear screams that you need to raise it to the next level, and not be scared to turn up the heat. She's obviously comfortable enough with you to touch you. So reward her and show her some Kino. Things like sarcastically putting you hand on her sholder her when teasing her are simple ways of showing that
your interested. You gotta assume the role of a man here and press the situation. Start taking the jokes into a push-pull fashion and be flirty. It's great to joke, but don't let her think your just feeling a friend vibe. Once you've done all this, built attraction and comfort, then I'd say your more then ready for a Kiss close. I normally feel like theres a natural feel when to kiss, but as you said you struggle with reading 'signals.' There are plenty of threads on how to kiss close situationally, with some routines on how to get there. So if you feel some canned material would help you, then it's there at your disspossal.
