Signs of a toxic relationship at the outset:

You show what your partner wants to see, not the real you. Controlling your partner and requiring obedience under the guise of care. Accusations. Advice on how to change or get better. Isolation from friends/family. Mood swings (abrupt change of mood). An excuse for a partner. Love is not ... - affection - pity - selflessness - passion - possessiveness - selfishness - the desire to give pleasure to another.
