Have you tried joining a dating app or doing a Meet-Up? Do you like following true crime? I just suggested to others to join Websleuths. And we are here for you.

First of all it’s admirable you are raising your son while dealing with grief. It takes a special person and you’ll probably find your relationship ends up closer than it would have been otherwise.
I understand what you are saying and I know how it can get to you. I have ended up alone because I get knocked down every time I try to reach out but I’ve learned to be mostly ok with it and enjoy the advantages. I’d be wary of dating apps until you are in a better place, that can be like drinking poison just because you are thirsty. Maybe you’d be lucky though.
Getting out in the community in other ways like clubs and meetups might be the way to go and getting involved in your son’s activities if you’re not already. Hang in there, things will get better.

You're not alone. I did it too, raised my daughter as a single mom, along with all the traumas that I had gone through. It sure wasn't easy. Listen, keep fighting because your son wants you around and you have to be strong for him. Just keep thinking about your son, that's your purpose in life right now. Once you totally accept that, everything else falls into place.
Stay strong. You can do it. I know you can. Your son needs you. Whenever you feel lonely, and thinking about your relatives and your wife, call one of your friends. Or write your thoughts to someone on here. We're here for you. Good luck and don't forget, stay strong!

You're human, no matter what the challenges are, we will get overwhelmed. It helps to talk about this, and when you do it out loud, you can hear yourself and help yourself. Acknowledge that this situation is challenging, acknowledge that you're allowed to feel this, and know that you will get through this. As a parent, fighting for yourself may seem pale in comparison to fighting for your child, in this manner, showing a child how you overcome this will also arm them with the skills and knowledge on how to manage it themselves.

you will be doing an amazing job raising your son, that takes alot of time and i guess patience, dont look to hard for something, things seem to happen naturally and someone will come your way if and when the time is right, for now get more friends in your life if you can, yep join some dating sites if its for you and just do things you want to do, your not alone being lonley, gosh my life is like a rollercoaster of emotions, your not alone and friends familys and even chatting on here all helps you to feel less lonley xx

Love to chat if you feeling lonely hi ❣️
