Search Results: does having sex hurt

Hi guys so i need advice on a friend of mine, i dont even know if we are friends anymore though. Ok so she has had a bit of a difficult life but that had never scared me away if anything its brought me closer.
Now my issue is in her behaviour, i have to point out that we did date for 3months and we were eachothers first sex partners, so i know she is not on her phone very often but when she does go on she completely ignores my messages for days on end untill i send another message that needs a urgent reply. Even after we broke up we were still bestfriends and i would be at her house every Friday to watch movies and tv series etc. But then at the begining of the year i got fed up with the response times and she said she would work on it.
The bext event after that is i sent a message the day before her birthday asking if it was possible if she could come get her gift from me as i had twisted my ankle that day she read that message and igonred me.
The next day on her brithday i sent her a message wishing her happy birthday but also stating how she hurts me by ignoring my message about her gift when i went through the effort of going out and buying it for her and could not deliver it when i was injured and i wanted to see her in person as well to wish her.
The reply i received was from another friend of hers who doesn't particularly like me saying that i am hurting the birthday girls feelings.
Having that message come from another person and not from my friend really hurt me again and from that day we have not spoken.
Was i in the wrong?

Oh right, I do remember it. It's that undying and legendary feel when no girlfriend.

I become one with that feel. It's that feel that feels like the cold void and dark emptiness, the eternal companion-lessness, the state of being undesired by the opposite sex.

Luckily my buddies @JudgmentDay and @HaveQuestions are helping me coping with it.

But still that feel when no girlfriend is recurring and it hits me right in the feels every time ;_;


I'm feeling it.
But for real now has there been a scientific explanation why having no girlfriend feels the way it feels like? I for sure know so far, that it has something to do with the heart. Does the heart experience some sort of oxytocin deficiency?
