SS, his coming over and snuggling with you is exactly what I meant by his using you as a cushion to make his fall easier. His asking to "friend" you, etc.
Use this anger to your benefit. Use it to invest in YOU, because he's not worth it (at the moment) and you are. Step away from investigating OW because that can lead nowhere good.
I'm sorry your financial situation limits your GAL'g. Does it cost to go to the beach? It would for me, but only because I live 1000 miles away. Do you have bikes? Can you go hiking? Do you have any meet-up clubs that offer activities for singles? Just anything to take your mind off of this and focus on anything else for a few minutes or hours. You're going to tear down your health and then you'll have even more problems.
He is not caring for you, so you need to care for yourself. (((())))
