A few months back my girlfriend said she's become good friends with this guy that isn't very social. He keeps to himself mostly and as such, she is one of the only friends he has. Now from my experience when it comes to a guy and girl becoming the best of friends in a short period, and spending a lot of their time together, the bond becomes strong because one of them has feelings for the other. And more than often, these feelings are kept discrete enough so that the other is oblivious to what is happening. Well, my girlfriend is oblivious. I came out straight with her and told her not to spend so much time with him because I had a hunch that he has feelings for her. She of course said I was being ridiculous and whatever. A few weeks later he starts asking her to go to the city with him. Just them two as friends. Well this is how she saw it anyway... I didn't let her, and thankfully she understood. Eventually he lets it out and says that he likes her. When speaking to me about it she wanted to start ignoring him but at the same time cherished the friendship they had. I didn't like the idea of it and thought a friendship that has lasted just one month wasn't enough for any serious attachments and so she should be able to let him go. Well apparently not. I instead agreed to her proposal to stop interacting with him as much, and declining any "friendly" dates. Fast-forward to a few weeks ago which should put it around 2 months later. I was over her place and while she was showing me stuff on her facebook I noticed how often this guy appeared to be chatting to her again. I checked her phone and while there were only a few inbox messages from him, there were a whole lot more outbox messages to him. Obviously she had deleted selected texts from her inbox. But she says she deleted them because I would get angry with it. Well, she's right about that. A few moments later while logged onto her msn he came online and started talking to her. Since I had control of the computer, I read his greeting and did something else to try and ignore it. I was furious... If that wasn't enough, he started drawing pictures on msn and sending them to her. Quite the artist he is, I give him that. But to see how much effort he was putting into it for my girlfriend, and while having noticed he asked her to go to the city with him pushed me over the edge. I went off at him. Amongst all the raging, I do remember him saying I should stop being so territorial and that I had won, she likes me and not him, so I should let it go. What really annoyed me is that yes if I weren't at all territorial then I'd be allowing him to step all over me and that would basically be saying, sure, try wow my girlfriend all you can, she is fair game and the best man wins. The fact that he also said that I win clearly indicates he was challenging me for her, which as far as I have seen, doesn't happen all that often amongst already established couples. But when it does, fists break loose. This time I enforced that she most definitely can't talk to him any more. She has to ignore him completely etc. etc. She still feels guilty about it and feels that same attachment for the friendship she felt months earlier. This is when she said that I should stop being so jealous about her and other guys. Am I really being over-protective here? I feel I have a right to act the way I did, but it probably depends on each person's opinion on the topic. By the way, I am pretty certain that she's completely faithful to me and we love each other dearly, so if she is to have any reason to say that I'm being too jealous about this, it's because she wouldn't cheat on me.
