You've only been talking since June and started dating in August. O.o
You don't love her, it's your with-drawl making you paranoid and making you think that she's a good partner for you. She can look in your facebook but you're not allowed to touch her phone? She got a text (or whatever) from another guy and hid it from you? She gaslights you and turns her piss poor behaviour around on you.? Most people wouldn't like seeing a strange guy/girl pop up on their gf/bf's phone if the phone owner didn't at least reply with something like: "oh that's my friend ___, I'll just let him/her know I'm busy with you."
Forget her. In about two to three more weeks you'll not give a shit about her. Work on getting through the steroid withdrawl and then start looking for someone who is a little less freak-the-fvck-out-over-nothing-like.
Now, having said that, your paranoia and your anxiety would be annoying to anyone. If you can't control that on your own and with cleansing it all from your system then please see your doctor because you'll definitely need professional help in being able to cope.
