Positive / Negative Relationships

Hey guys,Piece of advice required from those who can help or have experienced similar things would be appreciated.I have been offered the chance to enter into a relationship with what would be only my second boyfriend (I'm 26). He is great, we share loads of interests and he makes me laugh until my sides hurt.The only reservation I have is that he is HIV+ and I am currently Negative. He is currently "undetectable".Now, I consider myself well educated on the matter. I understand ART treatment and management of the condition much better than some of my peers as general sexual health and keeping informed has always been a priority. I understand that living with HIV is exactly that. Living. And that treatments have progressed to a stage where a general, otherwise healthy life is more likely than not. And of course, the role of condoms and keeping safe.However, having found myself in the situation I must admit that I have my reservations around making a commitment I fear I won't be able to keep.I suppose my question is, is it really plausible to maintain a negative HIV status while sexually engaging regularly with a partner who is positive? Is PrEP and condoms really viable solution?The other part of me thinks that having regular sex with someone who knows they are HIV+, and making the necessary "adjustments" to general sexual behaviour in order to ensure my negative status, may actually be safer than say, a random guy from Grindr who simply doesn't know theirs (or your app of choice, of course).Reddit, if you would share your experiences with me I would appreciate all the help I can get! I don't want to miss an opportunity with this guy, but equally I have my reservations.For the record, I intend to discuss this openly and honestly with him in the immediate future, but it would be nice to have informed and clear thoughts before entering the conversation.Thanks.
