<human>: My boyfriend is my best friend and I basically would choose to spend my free time with him over anyone. This year is our first year out and we are at separate universities. He told me about all his new friends - that being the boys, and I encouraged those relationships.

However, a couple of weeks ago he accidentally left his Facebook on my at my house and there was a conversation with a girl. I probably shouldn't have but I read the message to find he was calling the girl gorgeous and I thought the messages were flirty. I brought it up with him and he said he called everyone that even guys.. Which is true. But I didn't know who this girl was and why he was even talking to her..

Also recently he has been really defensive with his phone, and when I'm with him he got a lot of messages from a different girl. I asked him who she was and he said they were "good friends." But I've never even heard of this good friend until now? After 8 months of Uni he only mentions her now? 

I felt so insecure and felt like I wasn't enough for him. I feel like He now has this need to get close with other girls and to hide it from me to protect me and not upset me. I can't help but be jealous as I've only been the girl in his life for the last couple of years - bar is mum. I just feel like I'm in competition and I hate it. 

I brought it up with him again and I thought we sorted it out.  But her name keeps on popping up on his phone and it pulls me back into paranoia.  I can't help being upset, I want to stop but I can't. And when he try's to make me feel better.. He keeps on comparing me to her. I feel so uncomfortable.

Am I being a complete clingy girlfriend?how can I stop feeling like this ? Is it weird he talks to her so much despite and only tells me now about her? 

Please help 😥 thanks

Can you give me the gist of the text in a nutshell?
<bot>: My boyfriend didn't tell me about his "good female friend" as he didn't want it to be a big deal.. when really not telling me has made it a big deal.
