I have been trying to use some of the LRT methods like letting her come to me.
I try to act happy when we talk
I haven't mentioned a future in our marriage (outside of saying I think she should wait to make sure no regrets yesterday)
I send her only a text when I actually need to know something or when she texts me first
I asked her brother not to try to persuade her
I don't say I love you
the other day when she came over to tell me about her intentions to file I let her start the conversation. before and after it I joked with both her and her brother
that's really about it I think. not sure I'm doing it right or not though honestly. the part that worries me is if I pull back she might take it as ok he's let go now and I can continue on as I want and cease all contact at all but you are right I don't have a better plan
