Trying to make sense of a weird relationship situation.

(F39) is in an abusive marriage and heading for divorce but has been seeing (M48) for a couple of years. He has made it clear that he wants more from her, and during the conversation he asked how she would feel if he found someone else because his needs are not being met by the current situation (in terms of time and intimacy). She said she wants him to be happy and wouldn’t stop him if she can’t meet his needs, she said she would feel the same about him whatever he decided and said she could be anywhere and he would still be in her heart and she would still continue to message him.

Is it worth continuing to see her and investing any more time and emotion in her if shes willing to let him go and find what he really wants from her but with someone else instead and be willing to accept losing him from being present in her life? Am I missing something or does it seem a bit pointless to continue to see her if she has already memorialized him in her heart? Is this someone so badly damaged they would sooner cling on to ‘feelings’ instead of trying to have something more real with someone who actually wants them?
