<human>: So I'm going to a wedding saturday and to be honest we don't have a lot of income (me and my girlfriend), so I decided I was going to wear clean jeans (dark blue) and a pretty cool shirt (stripped black / grey with a collar something clean) for the wedding.

My girlfriend bothered me oh, I don't know how many times for me to put something else and I said no, because we don't have money for this. 

Then my sister went out of her ways and went to buy clothes for me (I actually have 0 problem with that) but then they came (mother, sister and her kids) to visit me at my appartment and said to try them on NOW. 

Again I have no problems right there but I had work to do. I'm a computer tech and sometimes I bring back computers I need to finish at my place for the next day.

It ended up with them: Mother / Sister and girlfriend agreeing with them with guild tripping for a good 5 minutes, sentences like: I spent 100$ for these clothes that's the least you could do, I see you once every 4 years.. and many more.

Now I'm not the type of person that just wants to upset someone for fun. I had stuff to do and I felt like they were just forcing stuff on me.

Can you summarize the given text in a few sentences?
<bot>: Sister bought clothes, didn't have time to try them on / I wanted to finish what I had to do before, following guilt trip. Am-I being inconsiderate or they're just being way too pushy?
