My daughter was 3 when my ex-husband and I divorced 23 years ago and I was completely honest with her about the whole thing. She did well even tho she didn't see him for several years,(I too moved in with my parents in another state). Always be honest with your child, never tell him a lie. They learn from you even at this age. If you are always truthful with him, he will be truthful with you throughout his life. My child, now 26, thanks me for always being honest with her and she is instilling the same honesty in her two sons now. Show him truth and respect and he will return it! Let him know you two can not live together anymore and that is why you are going to live with his grandparents, but that you both still love him just the same. No matter how hard it may be sometimes throughout his life never talk bad to him or around him about his daddy, just let him know how much you both love him. Even tho my daughter's father rarely called or sent her anything over the years I continued to tell her he loved her. Even after I remarried 3 years later, we both did not speak bad about her father or try to put her in the middle of any between us. Even if later you hear that maybe his father speaks bad about you try not to do the same thing. He will remember this as he grows, he will love and respect you more for it. Remember he is young and he will come thru this as you will too. Good luck with your new life and I pray God's many blessings and guidance for you!! B.
