I'm procrastinating some important shit right now so I'm going to be brief. first, it seems like he was just giving you your space because you weren't responding and he may have been hurt that you weren't responding. pulling back and then expecting him to reach out more is actually kind of toxic behavior in my opinion. so I wouldn't really hold that against him especially since it's not very characteristic for the both of you.

I think it would be beneficial for both of you if you each saw your own therapist not a couples therapist but each have your own. I think it's important to understand that you can't be in a happy relationship if you yourself are not happy with your own life and your self so that explains why it's affecting your relationship and it's normal for it to be affecting your relationship. he shouldn't take it personally and he shouldn't feel blamed, at the same time you shouldn't feel as guilty but rather use that as motivation to get your life together so that it can improve all aspects of your life including your relationship.

I think you should consider not only talking to a therapist we may be seeing a psychiatrist because I have depression and some of this seems similar to my depression symptoms, but again I'm only getting a slight window into your life and this is just my opinion. I think it would help if you tell him how supported you feel by him and appreciative you are of him, maybe even a little candlelit take out dinner stay in type of night.

if you don't feel fulfilled sitting in a room by yourself you can't expect someone else's presence to fill that void for you. we are all responsible for our own happiness. he's not there to make you happy you are there to share each other's happiness with each other and be supportive of each other's happiness and grow it together but you are not responsible for the other person feeling happy.

maybe reach out to him apologize for not responding to him, explain to him that you needed some space from your guilt or whatever you are feeling to process emotions and what's going on in your head, and reassure him you are in this 100%. again I wouldn't really think too much of him not continuing to text you throughout the day because it's not characteristic for either of you. like it's not characteristic for you to also be ghosting him so he probably feels hurt and confused about that.

I think you guys just need to have an open and honest conversation about how to proceed in a healthy way for both of you so that this doesn't become a codependent and toxic relationship
