Falling out of love?

My boyfriend and I have been dating for 2.5 years. The first year we were in college together, and then we graduated and have been long distance since. Over the last few months I have felt like my excitement for him has decreased, to the point where when we talk on the phone I am obsessively questioning whether I feel "enough" for him or whether my emotions are too flat. The first two years of our relationship were unbelievably happy, exciting, and loving. I am devastated at the thought of having to end this relationship, but as things are, I am constantly experiencing terrible anxiety and doubt over my love for him. I have even been taking an anti anxiety medication to cope with the crippling anxiety I feel but it hasn't provided me much relief. I wish I could be calm and ride this out and see if it's just a natural lull in the relationship, but my intense anxiety is making me feel like I need to make a decision right now. But it also don't feel strong enough to decide to break up with him. I just need some peace and reassurance, Or if anyone's dealt with this. Thank you

Long distance relationships are extremely difficult to maintain even for couples who have enjoyed years of marriage together. If you are starting to experience doubt and you can't get reassurance from your BF(or he may be reassuring you but it's not enough)then you need to listen to what your gut is telling you and then accept it. When you start to look back at the good times together, you are basically yearning for those times. If your relationship isn't producing those good times now regardless of distance and circumstances, then you either work on it or end it for your health's sake. If you are 100% certain your anxiety is caused by your relationship issues and you are on anti anxiety medication as a result, then it's screaming at you to take action. You need to discuss your feelings with your BF and get his reaction and opinion. If your relationship is meant to be, it will survive because you will both find a way to make it work. If not, you need to accept this and let it go.
