Well, look, if you are in a loving relationship with someone, you want those things done for you, and so does the other person. Relationships are utimately give and take. You can't force your kindness on people but kindness and niceness are ultimately very attractive qualities during key moments.
Yes, previously I was far too nice and forgave a lot, and I wasn't valued because they knew I'd always be there. Til I wasn't.
However, I'm not sure I give anything at the moment. I mean come on, how can I pretend to be invested in someone while shutting them down everytime they open up to talk about themselves? Or if someone brings me a gift everytime they see me, barely say thank you and never give them anything? Run significantly late and not even apologise? There's countless examples from the last 12 months of me being an asshole to men who have been perfectly nice to me, their main shortfall being displaying interest.
Like I say I'm overthinking due to the specific situation but I also feel like I need to change and not treat someone that treats me well poorly just because I've been taken advantage of in the past and am afraid of getting too close, or hurt. If you feel like you have to tell someone you're losing 'I wish I had treated you better when I had the chance' then something's not right.
I used to be someone that people described as 'a really nice person' and I want to embrace that side of myself a bit more in the dating context. Really nice people with good manners are actually very, very attractive.
