No romance

My husband and I have been married for almost two years now. Prior to us getting married, my husband always took me out on dates. He was also very romantic. Well, that has all changed. You see, a month after we got married, I became pregnant. Life changed drastically for us. He was laid off his job my fifth month of pregnancy. However, God blessed us. He was blessed with another job after being out of work for only a week. He doesn't make nearly as much money as he used to but we are still "making" it. We both work and we have two little people (he has a daughter from a previous relationship). I am tired all the time because I have a home to keep clean, clothers to wash, kids to tend to, and a husband that wants to have sex all the time. Here is my problem. I am a little scared with the way our marriage is going right now. We are NEWLY weds and I feel like we're an old married couple. We no longer have any romance in our marriage. He hasn't taken me out on a date since Valentine's Day and it's September for goodness sake!! I keep telling him that we need a date, but he doesn't seem to get it or even really care. I am so frustrated right now. I truly feel like crying. We were supposed to go on a date today (just a walk in the park). But @ the last minute, he made plans with his friends to go play soccer. Now I am sitting @ home on the internet seeking relationship advice b/c I haven't the slightest idea how to get my husbands attention. I feel like I am in a scary place right now. Honestly, this isn't the only issue with our marriage. My husband NEVER affirms me! NEVER! I don't know if I am ungly or pretty to him. Today, I purposely dressed really nice and he didn't say a word. :( He's not affectionate (but he's trying to do better with this issue). I am scared that I am going to do something I shouldn't. My husband likes to have sex and the sex is phenominal. Lately however, I feel a disconnect when I have sex with him. I don't enjoy it as much anymore. I am starting to wonder if there is something wrong with me. I love him but I just ...I don't know. A few weeks ago, I ran into my ex. He knows I am married but that didn't stop him from being fresh with me. He kept telling me how beautiful I was to him and he kept trying to get close to me. I make him back up obvioulsy and said my goodbyes. While walking away, my ex yelled his number to me and told me to give him a call from time to time. I didnt't think that I would, but I remembered the number and I called him. Since then, I've called him twice. We never talk long. We just chat for a little because I don't (and do) like the advances that he makes. My ex was really affectionate, romantic and full of compliments. HOWEVER, he was a dog. I found out he was dating another woman while he was dating me and we broke up. My husband is really a good man. He takes care of me and his kids. He makes sure that we have all the things we need. He's a very hard work. I trust him. He's never given me a reason to wonder if he's seeing someone else. He's a REALLY GOOD MAN. I am scared I am going to destroy my marriage. I decided that I will no longer call my ex. I've been wanting to tell my husband that I called him but I am scared. I am sure that he will get upset. Before we got married, the pastor told us to keep our marriage fresh and to never lose the romance. Well, our marriage is stale. Please help me! I miss us. I miss the way things used to be between he and I. Why do I have disconnect when we make love? Does anyone out there have any real advice that can help us?
