Hi Amadala,
It sounds more like a best friend relationship, rather than a romantic, intimate relationship. I feel you deserve to be happy. I understand you love him, but you deserve to be happy with the right man, and it’s not fair to him, for someone to stay with him and be unhappy, as I am sure you want the best thing for him, and you want him to be happy to with the right woman. It might be best to make a clean break, I know it will be difficult, but you both derserve to be happy.
