(English isn’t my first language so please excuse my weird phrasing) Today my boyfriend of 5 years told me, that 4 years ago he (almost?) cheated on me. He told me, that back then he invited a women he had a fling with before we were together to his house, he said he planned it as a friendly meeting. I always had a bad feeling about this woman and he told me they kissed and almost slept together but he stopped it and told her to go home. I don’t know how to feel about it, since it happened long ago and I don’t really want to end the relationship and our plans for the future over this. Still I’m very hurt and I don’t know how to act or feel about it, any advice?
