@Sunday16...Hi, there. I'm sorry to hear about your situation. A broken relationship can hurt a lot.
I wasted my "best" years on a man who lied and deceived me.
I'd like to modify that statement to say they were "best years of your life
so far." I think the future could hold a whole lot of great times for you.
I'll address the practical side of meeting others first. Yes, things can be expensive - I can't deny that. There are some less expensive alternatives, though. Some ways to meet people: take a course through the parks and recreation departments and local school boards (they are usually lower cost "interest courses" - not as expensive as college). Libraries have book clubs and sometimes a variety of other interest groups. Many community and charity organizations need volunteers. There are "Meet Ups" listed online for many cities around the world. If you have any religious leanings, a local place of worship can be a good place to meet others. If you are new in your city or town, sometimes there are "newcomers" clubs - to help newcomers meet people and become acquainted with the area and local services.
I am making the above suggestions based on my own experience. Your life is yours, and we're all different, so maybe my ideas won't work for you. But if nothing else is working right now, trying them doesn't hurt, right?
I was divorced eons ago. It took me a long, loooooong time to regroup and feel okay again. I wish I'd done more to get back out in the world sooner. That's water under the bridge though - looking back, regretting broken promises and kaput marriage, not doing more for myself sooner...just serves to keep me stuck with my wheels spinning. Getting out and trying things is more positive - some have been good, others didn't work. All were worth the try, though.
I'm so glad you reached out here. I have a feeling that you have
lots to offer the world. Perhaps you've not been feeling as though you're on solid ground to try things yet. I found that the ground for me became more solid as I tried to do more.
You are not old, btw. Mid-forties is still young - enjoy them!. I think you really deserve fun, love, happiness. I hope you find the support and care that will help you.
