My partner (whom I'm marrying in a few months) recently got in touch with a girl he used to know in school - apparently they had crushes on each other back then but never dated. She contacted him on social networking and they started emailing back and forth.

She was passing by Sg for a couple of days and really wanted to meet him up. I've seen a couple of their emails prior to this; she is very flirtatious. He had dinner with her, which made me uncomfortable but he assured me that they were just going to catch up on old times, and during dinner there was a fair bit of flirtation from her. Apparently she's married, but not happily. I'm pretty sure she doesn't want to cheat on her husband but she seemed very okay with creating emotional intimacy with my partner.

My partner tells me that he tried his best not to respond but at times he got drawn in to the emotions of things too, and he might have gone a little far with innuendoes. Yet he tells me that 'nothing happened'. I believe what he says and I believe the events he told me about. However, I feel that some things went too far - for example, she spilt her drink and was very embarrassed; she sat next to him on the couch in the restaurant, he put his arm around her and she leaned her shoulder against his head. Am I making too big a deal of this??

They had coffee again the next day and this time he was more platonic, but he did ask her "what was up with us yesterday?" and she told him what a gentleman he was, and how nicely he treated her.

To be fair to him, he did say some lovely things about me to her and he doesn't want to be with her at all.

It just makes me VERY uncomfortable that she's clearly very interested in him and keeps wanting to spend time with him. They spent the entire evening today chatting to one another back and forth on blackberry messenger - about the soccer apparently, but I'm sure there was more too, and mostly flirtation and innuendo from her side. She was meant to be out with friends tonight but she sure was replying to him very fast.

My partner thinks I'm making a huge deal out of nothing and that I'm being very unfair to him since he was faithful to me. I just snapped at him asking him why they're constantly chatting and he's pissed off with me for being pissed off with her.

I'm actually not that angry with him - I just feel REALLY angry with her. My anger with him is because he doesn't get why I'm so pissed off with her.

I don't know if I'm overreacting. Please help!!
