I frequently felt frusturated, resentful, angry with and ignored by my ex. But I still loved him and never thought of ending a marriage.
To me it's par for the course.. living with any one for a long period of time and with the normal stresses of life is gonna be hard. But anything else would be a fairytale.
A lot of the walkaways are just people chasing fairy tales.
Regarding dating...I dated some one 1.5 years after ex physically left. But we were and am not divorced. I wouldn't recommend it. But get that's it's something to experience.
For me, I was vulnerable and wanted too much to please. I demanded nothing. Almost to proove my husband wrong. I was an awesome partner bUT also very emotionally detached. I ended up realizing pretty quick that the relationship would not be good for me long term. Things ended after about 6 months.
I still don't regret it though for the experience and perhaps friendship that me and that guy might be able to have.
