Look at his body language. If he seems more interested in other men's appearances or has a lot of male friends with whom he is overly affectionate, it could be a sign. But this is not definitive.
One way could be to see how he reacts to other women. If he shows little to no interest in other attractive women around him, and his attention is mainly on men, it could be an indication. But again, everyone is different and some people are just more reserved or respectful in their interactions with the opposite sex.
Pay attention to his interests. If he is really into things that are typically more associated with the gay community, like fashion shows or gay - themed movies and he doesn't seem to have a heterosexual - typical interest in your sister, it might be a clue. However, people can have diverse interests regardless of their sexual orientation. For example, a straight man can also be into fashion. So, it's important not to rely solely on this.
First, you should be very careful. Don't jump to conclusions. You could try to observe his behavior more closely in a non - judgmental way. Maybe he just has some different mannerisms that seem 'gay' to you but could be something else entirely.
I don't know the specific story. Maybe he realized his true sexual orientation after the relationship with your sister ended. It could be that he had been suppressing his feelings all along during their relationship.
When I saw your question, the first thing that came to my mind was "The Special Love of the Greedy Princess". The female lead of this ancient romance novel, Lu Dingning, was also facing the fate of marrying a foolish prince. However, the difference was that Lu Dingning did not give up her own happiness because of this, nor did she let the retarded wangye become her burden. Instead, through her own efforts, she changed their fates step by step and finally realized her dream of becoming a materialistic princess. Not only is the plot interesting, but the heroine's courage and fighting spirit are also worth learning from. I hope my recommendation will be of some help to you. If you have any other needs, feel free to contact me. Muah ~
Communication is key. They need to talk openly about their feelings, desires, and any problems they might face. This helps in understanding each other better.
A bi man, Mark, found his gay boyfriend, Leo, through a mutual friend. Leo was really into theater and Mark loved music. At first, they were just friends hanging out at shows. But then, Mark realized he had deeper feelings for Leo. Leo also felt the same way. Their relationship was full of sharing different cultural experiences. They supported each other in their respective hobbies and careers. Despite some people not understanding their relationship because of Mark's bisexuality, they were happy together.
First, get to know your girlfriend on a deeper level. Learn about her dreams, fears, and what makes her happy. This way, you can be more in tune with her than her ex - boyfriend was. In terms of behavior, be more patient and understanding. If there were issues in her past relationship because of impatience or lack of understanding from her ex, you can be the opposite. Also, don't be afraid to show your vulnerability. It can make your relationship more real and intimate, which might have been lacking in her previous relationship.
I'm not entirely sure what you specifically mean by'sister gay my ass' as it's a rather unclear phrase. But if you mean a story related to sisters and homosexuality, here's one. There were two sisters, and one of them realized she was gay. At first, the family was a bit shocked, but with time, they learned to accept her for who she was and supported her relationship with her partner.
One problem is that it violates family ethics. In most societies, there are strong norms about family relationships, and this kind of relationship goes against those norms.
You could tell him a romantic story about how you two met and fell in love.
One possible reason could be that he was in denial about his sexual orientation while dating the sister. Maybe he thought he could be straight but later realized he wasn't. Another reason might be that he had a new encounter with someone of the same sex that made him understand his true feelings.
