<human>: My wife (29F) of 1.5 years and I (31M) have been having trouble since well before we got married.  Long story with many twists and turns, most of it some version of me being a jerk or uncaring.  I feel terrible about it and have tried to change, but I keeping sliding back into old habits.  No infidelity, physical abuse or stuff like that.  But various patterns of not caring about her or the relationship that have been wearing her down for years.  She is convinced that I don't really love her, and has given me a deadline to make her feel loved or else she'll file for divorce.

She has made it crystal clear that just shaping up in how I treat her won't cut it (although I need to do that too).  She requires something more, and honestly I don't really know what that would entail.  I'm thinking of writing self-examining love letters, but that's a pretty pitiful attempt.  Do you have any suggestions?  Thanks!

Can you give me the gist of the text in a nutshell?
<bot>: Looking for advice.  Trying to convince my wife I love her so that she won't divorce me and we can heal the relationship.
