When you love someone too much, you expect the same to be replicated to you.
If your partner does the contrary, he is a master manipulator who uses dishonest tactics to appear that they love you but are not.
Manipulation occurs when they play your mind games, disguised behaviours that look like love among others.
When he does these, he's just manipulating you:
1. Favourite lame excuses
When your partner aggrieves you repetitively, they use a common excuse like “...but I love you so much” that makes you forget instead of solving it. Your partner will defend himself/herself and never accept that they've made a mistake.
2. Threatening to kill oneself
An abusive relationship will have such threatening conditions that if you try to leave them or fail to fulfil certain things. When your partner does this to you occasionally, there's no love.
3. Unnecessary gifts
A master abusive partner will spoil you with gifts that looks lovesome but are uncalled for. He uses them as a means of persuading you to accept apologies for his horrible behaviours. He also turns very sweet, especially after arguments. Healthy relationships don't have concealed intentions.
4. Playing victims
They are good at twisting your mind by turning you as the victims of the mistakes they've done themselves. You end up apologizing for something you didn't do. In such relationships, you always carry your partner's burdens.
5. They appear to always criticize you. Here, your manipulative partner tries as much as possible to make you feel that you can't do without them. He makes you feel weak and insecure. His desires always come first even before relationship goals.
