So disrespectful, what do I do?

So there's this guy, we're trying To work something out, he's great and we have plenty and common. The downfall. His step mom hates me, hasn't actually met me yet but has saw me around and hates me. Making his dad unsure how to feel about me. His ex, is still trying to get with him and wants to fight me?¿ The day he an I hung out she asked everyone where we were until she found out someone she knew that was coming to hang with us too and followed her to us and would not leave us alone the rest of the night and constantly shooting me looks. I went to venture down stables as I'm going to be racing there next summer and other barns this summer, he too races except he cart races and I actually ride race. She was there being her obsessive ex self. And I went up to talk to him cause she walked away for 2 seconds and she's like scared of me so I like yeah I'll take advantage of this, so as soon as she stood beside him I was like "good luck on your race dear, I'll catch up to you after Tanya's last race and we can take those cute pictures you asked for, don't forget my hug" and she clearly wasn't listening. Anyhow after the race I went as chilled by the horse trailer with my pony and after awhile he came up and started talking about my horse and I'm so thankful I have a cute one and everyone's curious on how he can even move that fast with short legs😂 and were talking and laughing and making horse jokes and talking bout our races and along comes his ex with her friend and I soon had to leave so I was like "picture now let's go" and she sat close to him and I still stood with my pony waiting for him to say something, and he's like "cmon leave fluffy be and let's take this picture since you're leaving soon" and he scooted away fro bios ex and I sat with pride and she stormed off and I laughed. She came storming back with an older lady, late 30's early 40's, anyway the woman was like "yeah you can move now" and I was like "I'm taking a picture, sorry, who are you" and his ex kept shooting looks and I got closer to him and took more photos I'll post them below. What should I do though? His family barely knows me and already hates me because I took a picture with him? I'm confused, what do I do?
