dday, you need a mental vacation from the emotional meat grinder you have just be through. Give her a break. Appear like your having the time of your life to her and anyone who would report back to her. She needs to emotionally sober up and feel regret.
If was like this when you met her, she'd be history. For the moment you are done with her, not the boys, but her. Later in life you will be committed to someone again, her or someone else, but not now.
Build the truck, cool but not a real investment. Build that house, that's an investment. Finish it and live in it or flip it and live with ex if she wakes up. Use this time and energy, focus on creating. Take it from me, wallowing in self pity $ucks. Be the future you want.
