I am somewhat in your situation. I was with someone for years, still in love with this person. We finally bought a home and then a year later this person tells me they dont love me anymore and wants me to move, then moves his ex in my home, in my bedroom, sleeping in the home with my child. She has no problem being in my home. Right now I have no income and no way to pay rent, he keeps our child with him the majority of the time, I know this is so he does not have to pay child support. I use prayer to get thru this. This person abused me, put me down, talked about me bad, stayed out all night and never gave an explanation when he was coming home or when he got home, he sat in the house all day and would not even speak to me, giving me the silent treatment for over 6 monts, he is still giving me the silent treatment, calls our child and has our child relate a message to me if he wants to say something, this is still abuse.
Yes, I still am in love with this person, but dont have to be treated this way by anyone. It hurts to see that this woman is sitting here in my home, I am not allowed to come near the home, but I know that the enemy is sitting and smiling thru all this.
What I would do is leave him alone, pray, ask the Lord to bless you with the right person, ask the Lord to forgive you of your sins. Me and my child stay in a one bedroom while him and her enjoy our home, throw parties and sit and smile. This was so wrong but I am trying to follow what the Lord says "vengence is mine". Everyone tells me to fight for the home, the Lord will take care of this for me. I just keep depending on the Lord.
Depend on the Lord. Just leave him alone. Been kicked out of my home for over a year, have not dated anyone. Yes I get depressed and still in love with him and hurting. The Lord will guide you. Just follow what the Lord says, read your bible daily. Pray everyday. Dont do anything to this man, let the Lord handle it for you. Let him fight your battles. It hurts to be in love with someone and not be with them. You dont deserve the abuse and your kids dont either. Just turn to the Lord. Trust in HIM and he will see you thru.
