Hello. I can understand the feelings you maybe feeling at the moment. It can be very difficult to forget yourself at times.
Like your boyfriend said let’s start afresh. You can always do that, however that by itself can be a difficult. In my humble opinion, please seek help from any therapist who deals with relationship difficulties. You will surely get help.
Next Steps
Visit a therapist.
Health Tips
Connect with your boyfriend more frequently.
You may also discuss about your feelings with him if you like.
Focus on yourself more, in terms of hobbies or exercises.
Note: these are just wellness tips, it’ll be an add on or may act like painkillers to your feelings. You must ideally see a therapist for this. You will sure receive help :)
