Selfish Friend 😮‍💨

So I do have few friends or known people who just contact when they have to yap alot of negative things about their life or surroundings.These guys are purely negative.They make my mood from happy to guilty just by speaking.I am just bored with such kind of people.I would say am good listener but continuously listening to negative shit is hard enough. For example,I have a friend(F 31) lets call her 'S'.S was my teamlead at my first company.She is unmarried and looking out for match on matrimonial sites.So she was on call I just advised her not to rush in marriage matter as it can't be reversed if we choose wrong person.She was just raged out of nowhere told me that you are too straightforward & outspoken person you will not get any partner if this is your approach towards marriage.I wasn't wrong anyhow.Also,she is just confused between her ex partner & guy whom she met on matrimonial app. She always speak nonsense thing.She wants I should be available when she wants to yap about her daily life.Should I block her or stop responding her?Bcoz I can't take all this negativity.
