Dating someone with cyclothymia. need advice

It sounds as if you had a deep discussion, and that it's now left you feeling uncertain of which way forward you're heading.

Perhaps you could use this record of your conversation as a future point of reference for you to enable you to see if he is prepared to take on board fully what you've been saying? If he continues his behaviour, despite apologies, then you may need to ask yourself if you can continue in this way. As they say, words are cheap, easily said, and actions mean more. This is also true of your own actions. Each time you forgive him and remain with him after a demeaning comment, or controlling behaviour, you're sending him the message that your own words are cheap and meaningless and that unacceptable behaviour is okay and that you're prepared to take it.

If you do issue him with any ultimatums etc, then you need to be prepared to stand by them. Yes, it might hurt to end the relationship, but as long as you take care of your emotional health, and allow yourself space and time to grieve, you will survive and be okay.
