Relationship advice! Please!

Maria

So I have been dating this guy for almost 8 months ! He’s amazing guy ! He has his life together and works really hard ! When I first started talking to him everything was so great he would buy me flowers and always surprise me ! Lately he’s just been different! We hardly even talk because he says he’s always tired because of work ! We don’t really hangout because I have kids and my kids haven’t meet him yet ! But today he just threw it in my face that I’m not a normal girlfriend who can just hangout with him when ever ! I need advice idk what to do ! Do I stay with him and have him meet my kids or let him go? He doesn’t really pay attention to me as much as he did in the beginning of our relationship! And I was in a relationship with my ex husband for almost 8 years and I’m just scared for the same to happen again to me with my current boyfriend!
