Help! New to this...still hoping for R

Had an interesting experience last night - any input?? My future DIL had her bachelorrette party last night and I was invited. We had so much fun - I love her and her friends and a couple of friends mom's went also. But I forgot my cell phone at home. Figured everyone knew I was out with the party, so no big deal. I used DIL's phone to call S once, so he knew where I was and how to reach me if an emergency.
I got home and had 5 missed phone calls and two text's from H. The first text said he needed to talk with me about Father's Day morning(????WHY????) and the last text said "Appreciate the response" (sarcasim). I didin't get home until after 2am, so I didn't respond. In the morning, I just texted him, "Sorry, forgot my phone". From them on he kept texting me asking about when I got home, where did I stay, etc. I didn't give any answers specifically, but was polite and basically answered vaguely. He always trys to make it seem like he has some other reason for asking these kinds of questions. What's up with all that?? When I used to ask him anything about whereabouts and who with, he would tell me none of my business!
