Thank you all for your insight and advice on my post. In truth I am a little bit hurt,I know that if I told him this he would try and reassure me. But I won't say anything because it's his birthday and I don't want to make it about me. I will message him on Saturday and then leave it at that and enjoy my own weekend. I will play it cool and wait for him to reach out on Monday. If he doesn't then that speaks volumes to me. When I told him something the other day he said "I've rushed and been hurt in the past. If I'm going too slow then just talk to me".
It might seems OTT to some people,how I'm feeling..when I know that he hasn't met my family or my son. But on the flip side,I haven't had a casual party where the opportunity has been there. Maybe it seems hypocritical of me to say I want to meet his family and friends, when the fact is..if he had invited me I would have probably have said no (because I want him to enjoy it) but it would have been nice to feel like I mean something to him enough to want me there for his birthday. I will just try and chill out
