“As I write my girlfriend is on holiday with her two daughters and her ex-husband. She planned the trip to be with just the girls and when they went to pick up something from his house he was already packed and asked to leave with them. Not wanting to cause a fight in front of the girls, she said it was fine, and they left together. They are away now. She tells me she has no feelings for him and she wishes I were there instead. She wants to have a good relationship with the ex for the sake of the girls. I will pray to God and let Him guide me as He always has. If she is truthful, then everything is fine. In my gut, I know that boundaries take time to establish themselves. I have been trying to take my mom’s advice, “Get to know her, focus on yourself.” I feel at peace. We are neither married, nor engaged. We can change our minds at anytime. If I find that she has lied, or is untrustworthy in anyway, I will move on, having conducted myself in a kind, and unselfish way.”
I love your mother’s advice. Such thinking will save you a lot of pain and avert a lot of damaging anger.
Everything changes. You turn around and something has moved, someone’s charging higher prices, or neighbors you really like move to another neighborhood. Of course it happens in personal relationships too. This person’s in love (when he always thought it had escaped him); another person’s alone when always thought he’d love and be loved forever.
