we have been together for over a year when she decided to leave and return to a marriage that she said had died pre covid but that she had to stay in through lock down. When we met she had been alone for sometime and gradually as our relationship developed she became constantly happy and smiling, something her family and friends noticed and frequently commented on. We renovated her home together and she constantly told anyone who would listen that she was in love and wished we’d met sooner. I lived with her each weekend as I work away and she wanted me to move in permanently as did her children. When he found out about me he was suddenly interested again and has been seeing a therapist, promising to change. He is an older man, retired who’s just recently received another large payment for the sale of his business. This has coincided with her spending the last of the settlement she received. I earn a very good living and was happy to support her and the children but this obviously isn’t enough. She admits she loves me but won’t talk to me as she says she needs to focus on her marriage. Help please, can someone change fully? What do I do to win her back or do I just walk away, take the hurt and try and move on?
