So I was dating this guy back in November for about a month. Everything was going great we both really liked each other texted all day, every time we hung out he would always say how lucky he was and stuff like that. Then one week I noticed the texts became less and less and we just completely stopped texting for a week. I texted him after that week and just asked how he was and he never replied back to me, so it just ended like that, he also unfollowed me on instagram and Snapchat 2 months after. It's his birthday today and I was wondering should I just text him a simple happy birthday and maybe it'll get us back to talking again or not even bother texting him? I really liked him but I don't want to look stupid if he doesn't reply. Any advice would be great! Thanks
