Dear Lyn. If this man is acting like you say he is and walking over your boundaries, then it is clear - WALK AWAY. Call it off and WALK AWAY. It is not a healthy relationship and God gave all of us common sense to guard us.
Lord Jesus - I pray that You will protect this Mother of Three, who like me, also works a long day and has to do it all on her own. Strengthen her and let her know that You are husband to the husbandless and that YOU will grant her the desires of her heart as she seeks YOU and brings up her children to be Godly blessings to the world! It is SO hard to bring up our children and hold down a full day's job without help and so I pray that you will look down on this mother and guide her and keep her and her precious family protected and safe. AMEN.
