My relationship lately

Hello girls,

I guess I just got on here for advise of to vent I’m not really sure, but I want to talk about my relationship, about a couple weeks ago my boyfriend of 5 years mentioned to me that he feels out relationship has gotten stale and that we don’t have interesting and stimulating conversations anymore. Of course this made me feel some type of way and it was hard for me to hear this coming from him because I really enjoy our bond. And for a little while after that conversation I felt a very unnatural feeling around him like I didn’t know what to say or what he was thinking. It might help to mention that there is a 4 year age difference and I see him becoming more adult like than me and it really bothers me. Lately I’ve been feeling like he hasn’t been feeling my vibes and I don’t think there is a break up coming soon but I defiantly feel something weird. And I’ve been thinking a lot about this lately. It has like lowkey kept me up. like where is my relationship going? Do I bore him? Sometimes I feel like I’m the only one who even tries to start a conversation. And every time I try to talk to him about it he tries to change the subject ( this is not about him not wanting to talk about it he’s just really bad a communication and gets really weird about confrontation) he’s the type of guy that will start laughing when I bring something serious up. Anyway. I don’t know what do to. I feel lost and kind of alone. I love him dearly he’s all I ever knew and i plan on marrying him but sometimes he makes me feel like I’m not good enough. Or maybe I’m just being insecure. Who knows.. any feedback ?
