Is Saikawa Toxic Or Just Jealous?

So I've been seeing some discussions about Saikawa being toxic or just jealous. I think he is just jealous, but I am not sure if the jealousy he feels is still reasonable/normal or toxic.
Because of that I researched if jealousy is normal.

I know I am taking this fictional story too seriously by researching all of this, but I am just curious if Saikawa's reaction/jealousy is normal or toxic. (curiosity kills the cat ㅋㅋㅋ)
(I guess this will also help me in my future relationships ≧∇≦)

So lemme share what I've researched hehe

Based on what I've researched, jealousy is normal for a person who is inlove but there are also some kinds of toxic jealousy

There are six types of jealousy:

1. Pathological jealousy is an abnormal type of jealousy that often occurs as a symptom accompanied by a number of other mental disorders such as obsessive-compulsive disorder.

2. Romantic jealousy is considered to be a "usual" type of jealousy that includes a series of thoughts, feelings, and reactions caused by the actual or imagined threat to a relationship.

3. Sexual jealousy is a type of jealousy, which is manifested in the suspicion of physical infidelity.

4. Rational jealousy is different from other types of jealousy. In this type of jealousy, there is a real and reasonable doubt in a partner. Jealous partner behaves so as to prevent the loss of a loved one, but in a socially acceptable way, without intimidation, humiliation, threats and other forms of inappropriate behavior.

5. Irrational jealousy is a kind of jealousy that is very similar to pathological jealousy. It refers to a sense of fear and anger and often results in depression.

6. Intentional jealousy is a form of jealousy, which one of the partners can use with a specific function, for example as a specific tool against a partner or achieve some kind of benefit.


And I think Saikawa's jealousy is Rational or romantic jealousy which is normal for a person who is inlove.

(This is the first time I got hooked in a manga to the point of researching.(≧∇≦))
