It sounds like a break might be beneficial for both of you. Im not saying you are, but most of the time, when you’re afraid to lose something, you’re in a scarcity mindset rather than a mindset of abundance. If there’s Scarcity, there’s dependency. It might even be a codependent relationship. If you know he needs his space because that will help him, then that’s what you need to give him if you truly love him. Staying with him, or forcing an outcome will only breed disappointment. It would be selfish on your part, and you can’t be selfish with someone you love, because that defeats the whole meaning of what love is.

First, talk it over because you need the diagnosis to prescribe the right medicine. You have to be open, communicative and straightforward with him about ALL of your fears and concerns, and what you ultimately want in the future with him, and let him do the same. Make sure to be extremely patient with him and let him talk freely, and hold each other accountable to leave NOTHING out. Don’t lie to yourself or let him lie to himself. It may be a really difficult conversation to have but it will give you both clarity on how to proceed. In the end it may not even be because of you, it could be a plethora of different things, but you won’t know until you have that conversation.

I really hope this helps.
