Toxic relationship happens when both or either of the partner isn\'t loyal.
What causes toxic relationship is luck communication when certain challenges arise causing misunderstanding, it can even lead to breakups.
No one would wish to be in toxic relationship but conditions may force ie luck of money, this is the biggest threat, sometimes nobody would want to be in relationship without money so they just appear to be with you physically but spiritually they are dating someone else.
To avoid all this find a prayer partner not a player partner, this may help you alot, not everyone was made to be in relationship and make it last so your choiceabd luck will help.
Sometimes patience also leads to right destination.
Take your time and make a successful relationship.
