I'm 47 too old to start again. Don't want to be single !!
Sure you can... Ignore your feelings and take some action with courage.
It's been 1 month
Expect this is going to take a long time. Perhaps months and months. Feelings just don't go away. But it is really about how you decide to handle yourself.
Thoughts come before feelings. So work everyday a little on some good thoughts. It can be in many ways. Take some time for YOU. It can be in many ways. A new hobby, learning about change, you pick the subject and just do it.
I think you need to realize your partner has some real issues. First, if you are not married then they are not really commited. Obvioulsy, that is not what makes you feel good. So change. If your partner is not choosing to behave in ways to really focus on you, then change, don't enable.
You have years and years of good ahead of you. You make is so.. life is so beautiful.. this can be only brief point of unhappiness and discomfort. Temporary.. so make it so.
Heck, people pick bad mates. That is just a fact. Perhaps start focusing on empowering yourself and self discovery of why you tried to rescue a person in this new relationship. Say, OK, I made a mistake.. Heck, we all do. I will learn something from this about me. How I can change and be far stronger.
And yes, I will be strong for my father. He needs you strong. Show him who you really are under all this hurt... The real you.
This is what I want you to do. In the morning, you get up and say, "Hey, I am going to do one good thing that will make ME feel good because I love myself." then do it.. pick a flower and go smell it. Take a picture.. compliment a stranger.. rub your dads hands and tell him how much value you have in him and thank him. Buy someone a cup of coffee behind you... Those kinds of things.
And before you know it.. your strenght will come back to you. This will only be temporary pain.
And be wise.. If your partner is not being the most transparent, loving, caring, giving.. Then work toward finding someone who will or decide to be happy on your own.
Peace be with you.
