Search Results: jealousy in relationship

I personally think it is not acceptable to flirt with others while being in a relationship. I have the following arguments to support my statement:

A. The chance that the person you´re flirting with takes it seriously is relatively high. In fact, they might think they have a chance. If the s/o is faithful whats wrong with that? Well, this is science-based but the other person will try to pursue because they want what they can't get and it´s also proven that flirting only, causes a lot subconsciously.

B. Flirting is dangerous, it could slowly lead to more, without realizing one might replace his/her feelings. Humans aren´t like robots, being programmed and all.

C. I think it´s immature because it really isn´t that difficult to stay with one person.

D. A woman/man who flirts only with his/her s/o will be more desired and might create jealousy amongst others. I know this is a bit against A, but the difference between A and D is A gives a chance/flirts with those who desire him/her while D ignores the flirts and is only focused on their s/o.

E. Sign of strength (especially in this time where the majority is just easy) and perseverance when it comes to keeping values high.

F. The relationship between the couple strengthens immensely because ain´t no other person could interfere with their love.

G. Why risking it? Like what´s the point of flirting with others? There is no rational clarification for it. It has only disadvantages.

H. But I flirt for fun? There are other ways to have fun without risking a relationship.

I. One could be so loyal, but in my opinion, flirting decreases the loyalty a bit because one allows it to happen. One opens the door.

J. No matter how much someone trusts the other, self-esteem and/or trust will get damaged eventually. Especially when it happens often. Sadly it is uncontrollable and it has nothing to do whether someone is confident or not because if you care and love someone enough it will happen eventually. It´s inevitable.

I really could do with some help.
Having anxiety I tend to overthink and could do with some guidance.
I can't help myself or I feel physically sick, from stalking my ex boyfriends profile (we are still friends but he wants me back but I can't forgive him-long story).
It's a painful ride and I just can't stop looking at what girls photos he likes it makes me feel anxious not knowing. I'd rather be hurt and know that not know and be panicking.
I need help, I want to feel ok again.
Can anyone offer even the slightest bit of guidance.
PS: I have tried blocking, but I don't have the ability to keep it that way. This is a case of I need to help my mind.
