Most Helpful Girl
Just kissed? Don't worry about it. If there haven't been any other signs I wouldn't read that deep into it, you weren't going out very long when he kissed someone else. If you've been together all this time and there aren't any other problems with other girls, then I don't think there's any reason not to trust him. At the same time...trust your instincts. If you truly cannot get over this, and trust him again, then no one is forcing you. If you can't get past this, there's no future for you-- trust is a very important part of a relationship.
