How will you know if your boyfriend or girlfriend is really faithful with you???

You cant ever really know if your significant other is cheating unless you catch them in the act or they tell you. I think going with gut feelings is important as is communication. If you have a question, ask your bf/gf. If you dont feel they were honest rethink the relationship or ask more questions. Hopefully you will find peace in whatever answer they give you. If you are worried for no reason though, asking too many questions can push your bf/gf away if they are innocent

it's very hard to determine if your lover is faithful or not. but of course at first you can tell whether he/she is faithful basing on your observation if he/she has time for you and devoted as well. but still it's not 100% sure that that person is faithful because there are some who are good in hiding.

i dont give trust easily after my recent break-up. i hope you get why..., i think its just the woman's instinct to know if their boyfriends are faithful to them, im only speaking for the girls part... the girls just know it when they feel there is something wrong in the relationship... based on my experience... ;)
