Hello there ,
From what you have mentioned it appears to me that the relationship equation between you and your partner had changed. Whatever the reasons are for this it seems that he doesn't want to build on the relationship or continue the same (either temporarily or long term ) , thus he is shying away and avoiding getting intimate.
Please understand that humans need the emotional connection too for them to get physical and thus the lack of emotional connection here due to recent change is the reason for the lack of desire.
Next Steps
Please understand that you may have some repeating thoughts about sexual desire and wanting to get intimate as this is also a way of feeling close to that person. Stopping them abruptly may not be possible but however you can learn to accept them and realise you need not have an outlet with him everytime. The distress stops when you accept this and the change in relationship status.
Health Tips
Keeping yourself busy and occupied so that these thoughts are less . Trying to involve in hobbies and things that you like can help . Physical workouts and eating healthy and being with people you trust and love is essential. Give it time. Time heals everything. Learn to accept the changes in life and open your mind to new experiences and self development. If the thoughts continue then some meds for short term can help. All the best .
