Long time lurker first time poster here.
I (31) have been with someone for 5 months - it's been going really well, we've both been really keen, he asked me to be exclusive / not see anyone else around month 2, i said yes.
anyway, 5 months in, it's like a tap has been turned with regards to my feelings, and little things have started to annoy me, I feel disinterested and I dont want to see him.
This has happened to me in my previous 3 relationships but at around a year mark, and it literally happens overnight, and it's like i forget anything positive I thought about them, or why I really liked them, and just want to be out of the relationship. When I have ended the relationship previously, I have never really felt sadness or regret in ending the relationship or missed them (aside from the sadness that I have hurt them), and from their perspective, it comes out of the blue and is probably quite confusing and hurtful.
Before my current partner, I was single for around a year, and initially thought that it would be unfair to be in a relationship with someone when I know my feelings can change so quickly. however, I met current partner and thought he was different / it was different etc, but 4 months in, I don't think it is.
He is a really great guy, and I feel awful because I think that I will end up hurting him, and he's done nothing wrong or changed - it's all me. I also don't know what I can do to mitigate this in the future aside from not enter in to relationships?
