My girlfriend of 5 years and I went to visit some friends and she got totally wasted drunk. The whole evening she was sitting next to the other guy hugging him from behind putting her boobs all over him and wrapping her arms around his arm and squeezing his arm into her breasts and basically sitting on his lap. Later, I saw her running her fingers through his hair - twice. Of course she couldn't remember it the next day but insists it was nothing sexual and feels quilty and very sorry. I feel like, if she was touchy feely and wanted to rub her body next to someone it should have been me but she didn't, it was with the other guy. Was it just being drunk and should I forget it and stay together or did she know what she was doing? It felt like she was cheating on me. Ladies, please answer this, As a woman would you say this was NO accident?
