Cheftze: 1) Oisek B’mitsva, potur min hamitsva- being busy trying to get married is a mitsva so that would make him patur from tseddaka- I can check with a competent LOR on that one, but I’m pretty sure that is what they would say.
2) Tseddaka is a mitsva, but making people uncomfortable is an aveira… and I don’t think it’s the breslave bochurim’s place to push someone to do a mitsva at the wrong time and place at the cost of 2 other people’s discomfort.
