Thankfully thier are some women on here that do see my point. For 20+ years I never doubted until it was basically put in my face. I would have had no problem with her being his ex and him talking to her (occasionally) or hugging and kissing when we see her. The problem is the FACT that they both lied and covered up that they were ex's. I was told instead she was like a sister to him. She sent cards for different occasions, presents. Not to mention the texts and long calls.
So not to be rude or anything ANON and Wilhelm, I am not just "his girl" i am his wife. I have put over 20 years into our relationship and stuck by him through a whole lot. You don't even know half the story of what i have gone through with this man. Relationships are wonderful but they are also work, you have to work at them if they mean anything to you. Relationships are give and take, he has taken more than he has given but it was my choice to put up with.
However, I can assure you there is no way, no how anyone would put me out! Ever. I can tell that you must be a very young man to think that you would have that option. But since she would only be your "girl" or young herself it might work. If you ever get with a strong woman, one that knows who she is and what she wants, can take care of herself. One that doesn't NEED you for anything but loves you and wants you in her life, maybe you will realize, you wouldn't just be putting anyone out. Especially if you caused the doubt in the first place.
