tbh only a person who's never been in a relationship could ask this question no disrespect by that btw but a partner isn't just for sex when you like some one you like spending time with them and hanging out it doesn't have to take up money there are PLENTY of really really cheap and even free date ideas your partner is some one you look forward to seeing enjoy talking to and you care about them and they care about you there for your feeling whether they be happy or sad
