<human>: Can you condense the text into three sentences or less?

I have never cheated, nor will I ever cheat. I just wanted to make that clear before I started...

Alright... Starting at the beginning. I'm unhappy. I've been unhappy for most of this past year that I've been in my relationship... But unhappiness doesn't mean you don't love the person... However, he is the first person to be emotionally abusive towards me, he is the first emotionally abusive person I encounter, period. I've tried ending things before but always fall back like an idiot because feelings.

Things have been especially heated these past few weeks. Fights have been alot more intense... Mainly because he's become more insecure than usual about other guys wanting to ask me out and the such because of my job.

Moving onto the issue... I've been having a hard time sticking to my relationship through to therapy and everything... Not only because it's just a bad situation, but also because I feel like I'm straying. Enter the co-worker.

He kind of caught me by surprise. He went from being entirely unnoticed to always just... being there... out of nowhere. I swear I don't even know where it began... But I'm almost sure he has a thing for me, that or he's really friendly... But he's making my body feel electrocuted just by walking into the damn room. He touches my face and gives me a kiss on the cheek to say hi, that shit makes me feel like I'm floating. I don't want to feel like this for someone who isn't my SO... It isn't right. I feel horrible... At the same time, I don't know how to confront this situation... 

So please, guys, if you can refrain from ripping me a new one for how I feel and give me some advice on how to go about the situation, I would really appreciate it... 

I feel like a really shitty girlfriend, and I'm not... I'm kind, I'm giving, I'm cuddly and supportive, I'm understanding and laid back... But I'm doing this... Help.
