I can empathize how depressing this may be for you and give you props to seek out the help not only for your relationship and man but for yourself. Which brings me to my next question? Obviously you care for this man greatly and it shows through your compassionate words. Are you asking yourself though what makes you happy. Ultimately your happiness is what matters here and you are being a supportive fiancé. No discouragement please understand nor judgement from me only wondering who's giving you what you need to be as strong as your searching to be. I applaud you and your efforts and hope that you remind yourself that. Your bond with this love is what makes you so understanding and you should never beat yourself up for asking if your being to dramatic. you simply care and want the best for your man and your future with him. Again give yourself enough credit you will ultimately make the right choices here. Whatever that may be I wish you the best.
