What i do? I start to do more things that i love and that are healthy for me, socialize more with my family, pray more for others, i have joined a prayer site for singles (praying for spouse). Listening to relaxing music, dreaming about my desires of heart. When i dream about my future spouse, i don fix on one particula person because maybe i am waisting time. God knows who is the right person for me, it is much more then nice feelings or his/her looks etc...but God wants to join people who will serve them together in the kingdom of God. Try to have greater picture. Suffering for someone who is maybe not even our future spouse is waisting of time, energy, maybe even money, and the worse OUR ANOINTING. Believe it or not, you have ANOINTING on your life, to do specifique things that God called you to do. If you are depressed, you will not be able to comfort others, maybe even not pray for them (at least not efficiently). You need POWER from God for your every day life and for THE WORK IN THE KINGDOM OF GOD. And your power will LEAK when you will focus on the person who is not from God for you. I pray that God will give you strength and insight/understanding/wisdom to do things you must do. And to see who is your real spouse.
If you struggle with the person you have chosen, it is very very possible that she is not the one. Have you heard about ungodly soulties?
Please watch this:
FOCUS MORE ON YOURSELF AND LOVE YOURSELF MORE in this difficult season. I know you will struggle to that, it will be hard, but on the long run, you will be free and then find the LOVE OF YOUR LIFE. You do not need to ask acceptance and love from the other person if she doesnt want it, or if she is not able to give it to you...
There is a person who is THE FLESH OF YOUR FLESH AND THE BONES OF YOUR BONES and it will be not hard with her. God bless you.
I hope i have helped.
