It is hard for an addict to love. Most of them aren't capable of loving. They don't know how to love others. They are afraid of the feelings that come with love. They fear rejection and the feelings that come with being rejected. They are also afraid that they can't control their feelings. If they had a relationship with someone that was close, they wouldn't be able to control their feelings. If they had a relationship with someone that was bad, they might lose control and hurt their relationship. They would hurt themselves by doing that.
