Many victims of abuse dated or knew their abuser for less than six months before they were engaged or living together. The abuser will often claim 'love at first sight' or that you are 'made for each other'.
He/she may tell you that they have never loved anyone so much or felt so loved by anyone so much before, when you have really only known each other for a short amount of time.
He/she needs someone desperately, and will pressure you to commit to him/her or make love before you feel the relationship has reached 'that stage'. He/she may also make you feel guilty for not committing yourself to him/her.
