Relationships take a lot of work. Dating, online dating, and courtship all have one goal, to give us a Relationship to thrive in. It is hard to find a healthy, attractive, and willing partner. When you do, what happens next is the most important part. I work on relationship-building as a skill set. How can I be a better partner? How can I say with this person for life?
What I would like to propose is: give your body and soul what it needs/craves. Try and make healthier choices if you decide a meal or snack is in your best interest. And then, let it go, move on. Keep going. Do a bit more, eat a bit healthier, sleep a bit more, play a lot more, and listen to what your soul and body tell you.
Men are animals. Women are less-than-truthful. You might be better served to work on your lifestyle and fitness more than your online dating profile.
Here's the truth: I can't make you happier. I can't give you energy at the end of your work week or workday. I can't feel sensual when the feedback from you is "tired, overwhelmed, frustrated."
I learn something new and vital each time I'm in a long-term relationship.
Don't give up. Just because all of your previous relationships have failed, does not mean that the next date might be The One.
There is no bridge that's going to make our relationship work again, so my longing necessarily stayed in my own heart. There is no sense in sharing our desires and hopes when the other person is not available. It only makes it hurt worse.
Who shows up in my life next is a mystery, but I intend to give 100% of my available attention to her. This is how I do it.
There are plenty of single parents who use their kids to get out of almost every obligation. Even obligations to themselves, for say... exercise, dating, taking responsibility for their own actions. And I have been the dad who apologized for checking his phone when a text dinged while on a date.
