1.*Social***Check her social ** account to see if there are any signs that she has a boyfriend, such as posting photos with men, mentioning each other, etc.
2.*Mannerisms**: Observe how she interacts with other men, whether there are intimate gestures or special salutations.
3.*Moments**: Ask her friends about her relationship status.
4.*Wear jewelry**: Pay attention to whether she wears jewelry with special significance, such as couple rings, necklaces, etc.
5.*Timing**: Observe if she often has a regular schedule of activities on weekends and evenings, possibly with her boyfriend.
6.*Talking Topics**: Does she often mention a particular man or avoid the topic of a relationship when chatting?
It is important to note that these methods are not 100% sure whether a girl has a boyfriend or not, and everyone has different expressions and privacy concepts. The most direct way is to ask directly, but be careful about the wording and occasion to avoid embarrassment. At the same time, respect her privacy and don't interfere or disturb her too much, even if you know she has a boyfriend.
