Married but not inlove

Been married to my husband for four years now and we have been blessed with two kids. Problem for me is that I am no longer inlove with my husband. It’s confusing for me because I can’t imagine myself not being with my husband and having to raise two kids alone, I can’t imagine myself coming out of this marriage too because people will laugh at me again and I can see myself protecting my husband at all costs but I am no longer inlove with him. You know those butterfly feelings you get when you kiss, how excited you feel to be making love with your partner, how happy you feel when you go home and how you love going home... I don’t feel any of that anymore. I have spoken to my husband about this and even suggested that we do things together more often, maybe go on dates to rekindle things but he is always so busy. I don’t know what to do. If I’m feeling this week at just four years of marriage, how am i meant to spend eternity with him? This is my second marriage and I genuinely wish for things to work out...
