Oh precious heaven Jesus understands how hard this is but though you may be upset and hurting now, this will pass and you will know of peace and comfort to replace it.
All of us feel this way when we decide to go separate ways. It feels sad because we once enjoyed being close to someone and it is a loss. However, my love whatever we go through Jesus goes through it with us and we are never alone.
The Lord will bring you many people in your life, some perhaps for a little while, others for longer but in the case of boyfriends you need to be very sure that they are the person of God's choosing for you. Marriage is a committment that is life changing and God will prepare you and the right man for you to marry. We have to be patient about these things. Meanwhile enjoy getting to know Jesus better and the friendships you gain by being with others.
Everything will work together for good, so my love, feel at peace. You both felt the need to make this decision and God will help both of you to recover and know His love and joy once more.
Praying you are filled with peace and can look forward to the many more blessings that God has in store for you, just around the corner. Don't look back my love, look ahead to what God is going to give you. He never closes one door without opening another one.
Be strong in Jesus, for in Him you are.
Big hugs, and love in Him
Gentle-Heart
You will be in my prayers, and may the Spirit comfort you, and give you peace
