Looks like you are struggling with a number of things coming together. You seem to be finding yourself torn between what your parents might approve of and what you want for yourself. And even with the relationship, you seem to have some doubts and concerns.
It seems like you have strong reasons to want to hold on to the relationship, considering the kind of person he is and how loved you feel by him. At the same time, you are worried. You mentioned a concern of not being able to feel sexually attracted towards him anymore, and that can indeed be worrisome. However, it can be resolved. I wonder if you have been able to share with him and have a conversation about it? It might be helpful to try and address it, to understand what the issue might be, and to what extent can it be resolved by you together.
The other concern you mentioned is the long distance relationship and the trust issues you have been experiencing within that. Long distance relationships can be challenging, and the fact that both of you have made it through for over seven years does say something about your attachment to each other and intent from both of you to stay together and make it work. What do you think? You said that some hints you found were proved wrong every time… is it happening that you are seeing things or worrying about things that may not be happening? There might be a reason for that. It could help for you to explore where your trust issues might be coming from, and see how you could try and manage them, so that they don’t overwhelm either of you or become a source of stress in your relationship.
Your concerns about whether or not your parents would approve of your relationship are understandable. It also shows that you care about your family and how they feel. And you also care about the relationship. The fact that you are bothered about the issues that might come up is probably because you care for things to go well on both ends. And that is fair. You could work towards that. If you believe that the relationship is meaningful to you; if the both of you are serious in your intent to take it forward, then external factors (like how well-to-do your families are, or other factors) need not get in the way of your decision. You could try and work it out with your families and maybe they will eventually be able to see what you see in it.
If you yourself are doubtful of whether you even want to take this relationship forward, then maybe you could try and understand where that is coming from and take decisions accordingly. Remember, it is important that you are able to make your own choices according to what is meaningful for you.
