2. The man sounds kind yet has bad tantrums
The guy is sweet and talks nicely to you. This is no doubt very good. But it is very suspicious if at times you see him have tantrums. Even if this happens only once you should think very well before you finally decide to create a relationship with such a person. If he cannot control his anger, it may cause very serious issues between you two in the future. Avoid abusive relationships at all costs.
