do you ever make the mistake of giving too much to somebody, when they don't give the same back

i mean as regards as interactions go, it's just the way i was brought up, my mother was and still is very loving, over mothered me and brought me up very well, and me, i am very loving person, giving of myself.......but there's times online, when i make the mistake of being too giving to someone......and that other person doesn't give the same back or reciprocate the same sentiments? or just doesn't respond at all........then i feel angry that i was maybe too friendly with that person in the first place and angry that they didn't give the same back or didn't respond at all?

all i want to do is try to make a friend or two, find connections......what do you think the answer is?
