And she is gradually getting less and less loving and caring towards me..
She tells me I'm paranoid but I don't think that is the case

This isn't going anywhere. End it! She's clearly not a good match for you, or she's using you.

Wow, it's like I'm hearing my past self right now. Take it from someone who has been in the same exact situation you've been in. Dump her... right now... go do it.
You will never be able to trust this girl. She couldn't tell you she was hanging out with other guys, she's threatened to break up with you for bringing it up. She's a control freak and manipulating you.
What she is doing, is using you as a backup plan. She's going to flirt and talk to plenty of other guys until she finds the one she wants. She's using you as a fallback until that time. As soon as she finds the right guy, she'll break up with you.
Trust is the most important thing in a relationship. If you can't trust her, don't be with her.
Save yourself the pain and let her go. It'll be hard but trust me, you'll be glad you did. When you do break up with her, go out and start partying yourself. Meet new women and have fun. Enjoy yourself and find someone who's worth your time.
Oh by the way, if you break up with her, she'll probably get really pissed off so definitely make sure you got your shit out of her place before you do. Be warned though, she'll be calling you back in a few week - I guarantee it. Ignore her.
tl;dr - grab your balls, be a man and drop her for someone who you can trust and is worth your time.
