Middlepath- I know this is weird to say- but you sound like an AMAZING guy!!!
I really always agree with so much that you say and I also have this “problem” and people always tell me- you can do things for yourself sometimes.. and i do, but when others need things- i like to help them out first- these things dont bother me. i think it’s fine. Yes, we shouldnt go to an extreme with any middah (take the middle path 🙂 ) but it doesnt seem like giving to other people the way you are is an extreme. you arent giving all your last pennies to tzedukah, and you arent giving up everything for everyone else- just everyday things which is normal and amazing. everyone should be giving up their spot in line if someone else seems like they are in a huge rush and needs to be somewhere really important. (at least that is how I feel..) You seem very yashar and I think you should keep up what you are doing and you wont have a problem in marriage…
