Is forgiveness impossible?

[gr8 day 2B alive]

I have a few post going around but thoguht I'd try in here for a WAW's viewpoints.

W and I have been separated for 4 months now. She left b/c she felt rejected in M b/c we didn't have an active sexlife.

We wanted to meet yesterday to talk and she started by saying we should see a counsler to draw up a post marriage agreement.

I agree with her decision then talk for awhile,

During our convo I said to her she needs to forgive me before any progress can be made. She has her defenses up and she's not accepting some changes I have made.

Any WAWs out there who forgave their LBH?

What can I do to show her I deserve to be forgiven??
