If Ise doesn't love Rias, then he wouldn't have wasted till now to confess to the other girls. The fact that Ise only focused on loving Rias for such time itself shows her importance to Ise.

Who was the first girl Ise proposed too? Asia? Koneko?

Besides most of the other girls needed an external factor to propel Ise or themselves to confess. Ise only accepts that he loves Akeno when Baraqiel demanded Ise to leave Akeno. Xenovia and Irina proposed to Ise, not otherwise. Vidar had to play cupid for Rose and Ise. Overall, most of Ise's confession to the other girls are triggered by external reasons while Rias was the one he proposed too without needing anyone to push him to it.

Also, even if Ise does marry and fall in love with other girls, is Rias truly against it. I'll just put one person to talk about, easiest to talk is Akeno.

Akeno is Rias' closest friend, Rias probably even consider Akeno her family. While they bicker much, i doubt either of them have actually consider truly monopolizing Ise from each other. Rias views Asia as her younger sister, and even knows Asia loves Ise before her. She also understands that Ise cares a lot for Asia's well being. Wo
