All I can share with you is that heartbreak takes time to wear off. Falling in love is just a mystery. There is not logic to it. And when you are in love, everything seems easy and blissful. A comfort level and connection develops like nothing you have experienced before with anyone else. Your mind is so in tuned with them and you find yourself thinking about them a lot. There is a sense of stability and security based on my experiences.
It is difficult to remain in love when a line such as honesty has been crossed. Being deceived is not an easy thing to accept especially when you've been together for so long.
I can relate to you quite well. Without telling you what to do, I will say mourning is normal and will end when you reach an understanding of why things ended the way it did. Leaving a lover who has betrayed you is not an easy choice but better in the long run. Walking the lonely road is not where anyone wants to be but it’s normal and part of the mourning process.
I usually reflect and read and write to get things out of my mind. I also paint and exercise a lot. But finding ways to express myself allows me to fill the gap of not being able to talk to the person I miss. It’s never the same but now is the beginning stages of new growth. A new foundation of living is being built from the flames and ashes of a prior love. In time, the emotions will fade. It just takes time and courage to face it until you are ready to just stop thinking and feeling about it.
There are many ways to cope with it. But choose what is right for you. Embrace this moment of transition through reflection and meditation until you find inner peace with your decision.
We learn about ourselves in relationship with others.
