So, my boyfriend was in another city for work. In the evening he went out for drinks with people from the conference and after he was supposed to go to a friend's birthday party (the friend lives in that city).

While he was there, he was told that a female friend of his (who lives in another country) happened to also be in that city. They are more or less recent friends and have only seen each other 4-5 times before. I've met her once. He texted her and she came and meet him at the conference drinks. They then spent the rest of the night hanging out and drinking. She went with him to his friend's birthday party.

They got so drunk that the next day he was so sick that he didn't make it to meet one of his other friend's new baby.

I didn't think much of it. But last night he was unpacking and he came across some photos that him and his female friend had taken in a photo booth in a night club. He was excited by the photo and said "oh my god, I had forgotten we even took these pictures", I stretched out my hand to see the photo and he hesitated a little but gave it to me.

In the photos, they're laughing, leaning on each other, she has her arms around him and their faces are close together. I said "looks like you had loads of fun!" but he didn't respond, there was an awkward silence, he took back the photo and then left the room.

I felt a pang of jealousy when I saw the photos! I very calmly asked "did something happen last night?"
He got very angry. He started saying that I don't allow him to have female friends and that this is ridiculous. I have NEVER said anything about any of his female friends, never.


(He has omitted hanging out with ex-girlfriends before and being late to meet me because he was with one of them, which I only found out because then he'd slip up about seeing them. And I had never said that it wasn't ok to see ex-girlfriends so there would be no reason to lie/omit it.)

Now, I feel like he was lying about the night.

Am I overreacting?
